Issue description

The issue is described in detail in #4175, but it was locked so I could not reuse it. While building from master makes this better, it's still not solved. Some of the pastes still emit the escape sequences and end up on a single line. In fact, it's more inconsistent now than before, as before all pastes would inline and emit escape sequences and now some work, some inline without escape sequences and some emit escape sequences.

Here's an example of be pasting the following contents three times in a row.

abc
def
123
456

The output:

abc
def
123
456
abcdef123456abc
def
123
456
^[[201~

As you can see, the first paste is correct. The second paste is inlined without escape sequences and the last paste in mult-line but with escape sequences being emitted.
