Simple here documentish syntax for REPL paste.
This makes it easier to paste a block of script
(as opposed to transcript).
It also means you won't accidentally ctl-D out
of the REPL and then out of SBT and then out of
the terminal window.
```
scala> :paste < EOF
// Entering paste mode (EOF to finish)
class C { def c = 42 }
EOF
// Exiting paste mode, now interpreting.
defined class C
scala> new C().c
res0: Int = 42
scala> :paste <| EOF
// Entering paste mode (EOF to finish)
|class D { def d = 42 }
EOF
// Exiting paste mode, now interpreting.
defined class D
scala> new D().d
res1: Int = 42
scala> :quit
```
Use `-` stripmargin character to indicate trim (i.e.
remove leading indentation). `<<` looks more like
shift left, but is already the standard here doc sequence.
Indentation is often mangled by pasting, so trimming
normalizes lines for error messages. The entire paste
text was already trimmed as a whole.
`-Dscala.repl.here` provides a default end string, which
is unset unless specified.
```
scala> :pa <-
// Entering paste mode (ctrl-D to finish)
def g = 10
def f! = 27
--
// Exiting paste mode, now interpreting.
<console>:2: error: '=' expected but identifier found.
def f! = 27
^
```

I like the change, but I'll wait for a few more reviews before merging: it will be harder to change once it's in a release. |

LGTM, even if only to make it easier to test paste mode. |

It's really just so I can create an issue over at ammonite and comment, "Fixed in Scala REPL." |

thanks Som! one more ctrl-D ejects you from your office window — we can't have that. |

rather than attempt to resolve merge conflicts in the Eclipse config, the log shows that I merged ae5f0de with `-s ours`. (I have invited Mike/performantdata to submit a followup PR bringing the Eclipse stuff into a good state on 2.12.x.) there were no other merge conflicts. in test/junit/scala/collection/mutable/OpenHashMapTest.scala I had to make the following change to fix a test failure: - val field = m.getClass.getDeclaredField("scala$collection$mutable$OpenHashMap$$deleted") + val field = m.getClass.getDeclaredField("deleted") % git log --decorate --oneline -1 origin/2.11.x | cat ae5f0de (origin/HEAD, origin/2.11.x) Merge pull request scala#4791 from performantdata/issue/9508 % git log --decorate --oneline -1 origin/2.12.x | cat c99e53e (HEAD -> 2.12.x, origin/2.12.x) Merge pull request scala#4797 from lrytz/M3-versions % export MB=$(git merge-base 2.12.x origin/2.11.x) % echo $MB 42cafa2 % git checkout -b merge-2.11-to-2.12-oct-16 Switched to a new branch 'merge-2.11-to-2.12-oct-16' % git log --graph --oneline --decorate $MB...origin/2.11.x | cat * ae5f0de (origin/HEAD, origin/2.11.x) Merge pull request scala#4791 from performantdata/issue/9508 |\ | * 08dca37 (origin/pull/4791) SI-9508 fix classpaths in Eclipse configuration * | fe76232 Merge pull request scala#4798 from performantdata/issue/9513 |\ \ | * | 9c97a7f (origin/pull/4798) Suppress unneeded import. | * | 30d704d Document some OpenHashMap internal methods. | * | 1fb32fc SI-9513 decrement "deleted" count in OpenHashMap.put() when slot reused | |/ * | 14f875c Merge pull request scala#4788 from dk14/patch-1 |\ \ | * | 42acd55 (origin/pull/4788) explicitly specify insertion-order feature in docs | / * | 68ce049 Merge pull request scala#4771 from som-snytt/issue/9492-here |\ \ | * | f290962 (origin/pull/4771) SI-9492 Line trimming paste | * | bc3589d SI-9492 REPL paste here doc | / * | 9834fc8 Merge pull request scala#4610 from todesking/spec-implicits-remove-obsolete |\ \ | * | 46009b1 (origin/pull/4610) Add view/context-bound parameter ordering rule | * | 6eba305 Spec: Implicit parameters with context/view bound is allowed since 2.10 | / * | d792e35 Merge pull request scala#4789 from janekdb/2.11.x-param-names-predicates-operations |\ \ | |/ |/| | * b19a07e (origin/pull/4789) Rename forall, exists and find predicate and operator params. |/ * 648c7a1 Merge pull request scala#4790 from SethTisue/issue/9501 |\ | * 40d12f1 (origin/pull/4790) SI-9501 link README to Scala Hacker Guide * e0b5891 Merge pull request scala#4786 from performantdata/issue/9506 * 39acad8 (origin/pull/4786) SI-9506 suppress Scala IDE-generated files in the Eclipse project dirs * 74dc364 SI-9506 suppress Scala IDE-generated files in the Eclipse project dirs % git merge fe76232 Auto-merging src/repl/scala/tools/nsc/interpreter/ILoop.scala Auto-merging src/library/scala/util/Either.scala Auto-merging src/library/scala/runtime/Tuple3Zipped.scala Auto-merging src/library/scala/runtime/Tuple2Zipped.scala Auto-merging src/library/scala/collection/parallel/ParIterableLike.scala Auto-merging src/library/scala/collection/immutable/ListMap.scala Auto-merging src/library/scala/collection/TraversableLike.scala Auto-merging README.md Merge made by the 'recursive' strategy.

there were merge conflicts in the Eclipse config that I resolved with --ours. I invite @performantdata to submit a followup PR bringing the Eclipse stuff into a good state on 2.12.x. there was a test failure in test/junit/scala/collection/mutable/OpenHashMapTest.scala due to the 2.12 compiler emitting the field backing a private var differently (with an unmangled name). Lukas says the difference is expected, so I just updated the code in the test. there were no other merge conflicts. % git log --decorate --oneline -1 origin/2.11.x | cat ae5f0de (origin/HEAD, origin/2.11.x) Merge pull request scala#4791 from performantdata/issue/9508 % git log --decorate --oneline -1 origin/2.12.x | cat c99e53e (HEAD -> 2.12.x, origin/2.12.x) Merge pull request scala#4797 from lrytz/M3-versions % export MB=$(git merge-base 2.12.x origin/2.11.x) % echo $MB 42cafa2 % git log --graph --oneline --decorate $MB...origin/2.11.x | cat * ae5f0de (origin/HEAD, origin/2.11.x) Merge pull request scala#4791 from performantdata/issue/9508 |\ | * 08dca37 (origin/pull/4791) SI-9508 fix classpaths in Eclipse configuration * | fe76232 Merge pull request scala#4798 from performantdata/issue/9513 |\ \ | * | 9c97a7f (origin/pull/4798) Suppress unneeded import. | * | 30d704d Document some OpenHashMap internal methods. | * | 1fb32fc SI-9513 decrement "deleted" count in OpenHashMap.put() when slot reused | |/ * | 14f875c Merge pull request scala#4788 from dk14/patch-1 |\ \ | * | 42acd55 (origin/pull/4788) explicitly specify insertion-order feature in docs | / * | 68ce049 Merge pull request scala#4771 from som-snytt/issue/9492-here |\ \ | * | f290962 (origin/pull/4771) SI-9492 Line trimming paste | * | bc3589d SI-9492 REPL paste here doc | / * | 9834fc8 Merge pull request scala#4610 from todesking/spec-implicits-remove-obsolete |\ \ | * | 46009b1 (origin/pull/4610) Add view/context-bound parameter ordering rule | * | 6eba305 Spec: Implicit parameters with context/view bound is allowed since 2.10 | / * | d792e35 Merge pull request scala#4789 from janekdb/2.11.x-param-names-predicates-operations |\ \ | |/ |/| | * b19a07e (origin/pull/4789) Rename forall, exists and find predicate and operator params. |/ * 648c7a1 Merge pull request scala#4790 from SethTisue/issue/9501 |\ | * 40d12f1 (origin/pull/4790) SI-9501 link README to Scala Hacker Guide * e0b5891 Merge pull request scala#4786 from performantdata/issue/9506 * 39acad8 (origin/pull/4786) SI-9506 suppress Scala IDE-generated files in the Eclipse project dirs * 74dc364 SI-9506 suppress Scala IDE-generated files in the Eclipse project dirs % git merge ae5f0de Auto-merging src/repl/scala/tools/nsc/interpreter/ILoop.scala Auto-merging src/library/scala/util/Either.scala Auto-merging src/library/scala/runtime/Tuple3Zipped.scala Auto-merging src/library/scala/runtime/Tuple2Zipped.scala Auto-merging src/library/scala/collection/parallel/ParIterableLike.scala Auto-merging src/library/scala/collection/immutable/ListMap.scala Auto-merging src/library/scala/collection/TraversableLike.scala Auto-merging src/eclipse/test-junit/.classpath CONFLICT (content): Merge conflict in src/eclipse/test-junit/.classpath Auto-merging src/eclipse/scaladoc/.classpath CONFLICT (content): Merge conflict in src/eclipse/scaladoc/.classpath Auto-merging src/eclipse/scala-compiler/.classpath Auto-merging src/eclipse/repl/.classpath CONFLICT (content): Merge conflict in src/eclipse/repl/.classpath Auto-merging src/eclipse/partest/.classpath CONFLICT (content): Merge conflict in src/eclipse/partest/.classpath Auto-merging src/eclipse/interactive/.classpath Auto-merging README.md Automatic merge failed; fix conflicts and then commit the result. % git checkout --ours src/eclipse/partest/.classpath % git checkout --ours src/eclipse/repl/.classpath % git checkout --ours src/eclipse/scaladoc/.classpath % git checkout --ours src/eclipse/test-junit/.classpath % git add -u % emacs test/junit/scala/collection/mutable/OpenHashMapTest.scala % git diff test/junit/scala/collection/mutable/OpenHashMapTest.scala | cat ... - val field = m.getClass.getDeclaredField("scala$collection$mutable$OpenHashMap$$deleted") + val field = m.getClass.getDeclaredField("deleted") ... % git add -u
