[PATCH 2/2] input: do not auto-indent when something is pasted into nano from outside

[Benno Schulenberg]

Also, do not break overlong lines and do not convert tabs to spaces.
In other words: accept an outside paste as literally as possible.

This fulfills https://savannah.gnu.org/bugs/?40060.
Requested-by: Egmont Koblinger <address@hidden>

And fulfills https://savannah.gnu.org/bugs/?57527.
