It was inspired by the discussion starting with

http://lists.gnu.org/archive/html/bug-readline/2015-05/msg00007.html

The idea is to optimize pasted input using the assumption that it will be
mostly composed of characters that map to self-insert, and you can batch
read those characters and perform one display update.

The way to test whether or not a character will be inserted into the
editing buffer is to see whether or not it maps directly to self-insert.
If that's the problem, there will have to be a cygwin-specific fix; it
works elsewhere.
