[Bug-readline] A bug and a patch

[Nikolay Shirokovskiy]

Hi, everyone.

I watched a misbehaviour of readline for a long time and recently decided
to find out a way to fix it. I thougth it would be some proper configuration
of system etc but it turned to be a bugfixing.

DESCRIPTION
I have a archlinux installation with readline-6.2 patchlevel 2. The
problem is that
option 'completion-ignore-case' doesn't work with Russian characters
in ru_RU.utf8
locale.

There is a simple patch in attachments that fixes it. By the way it
fixes the same problem
for combination of 'completion-ignore-case' and 'completion-map-case' as well.
I also send a little test project that checks the function patch
touches. Beware
there are some Russian filenames there!)

This is my first patch to opensource ever.
