The ultimate upstream is an operating system, but there's also a
middle-man who maintains a portable distribution of this one library
from that operating system.

The changes seem reasonable as far as they go. They seem to have been
fixing a legitimate issue with the first one, but it's definitely
incompatible with what python does. It removes and reinstalls the
callback between every input line, and doesn't want to lose all the
state (including history) every time it does that. This might be
considered a strange approach, but it does work fine with gnu readline,
which is what they're emulating.

With the second one, they seem to have just not thought through the fact
that things other than filenames might be completed. It's not a bad
idea, but the escaping somehow needs to only be applied to actual filenames.
