Looks like we've got some merge conflicts to sort out. Are you happy to take a look at these @jridgewell? |
The only time the names vector has more than one `Name` in it is when parsing contiguous short options (`-abc`). We would continue putting `Name`s into the vector until we hit a short option that takes an argument. At that point, we break, so we can process the argument. So there's no point to reprocess the head of that vector, we already know they don't take arguments. Only the last one matters.

This commit reverts three recent PRs to the `getopts` crate. One of the main consumers of `getopts` is `rustc`, which isn't allowed to have breaking changes. In rust-lang#82, however, a breaking change was landed. It looks like rust-lang#83 builds on this change, and while rust-lang#81 seems unrelated the diffs were somewhat tangled.
