These patches should fix the Unicode line editing issues in msys bash for most users (see ).

The major part of the patch series was backporting the multibyte to wide char conversion functions from newlib 1.20 / cygwin 1.7 to the current msys.dll (based on newlib 1.9), so that bash could be compiled with multibyte support.

I'll send another pull request for the devel branch (binaries only).

Sorry I forgot to clarify the 'most' in 'most users'.

The console input code in fhandler_console::read currently doesn't decode UTF-16 surrogate pairs (> \u0ffff, e.g. CJK extensions). I couldn't find any hint on how ReadConsoleInputW transmits these (not even in cygwin's fhandler_console), and as I have no way to test this either, I'd like to leave this one to CJK users who actually have that problem.

@stevenkling So if you want this, you could help by

1) reviewing the code,
2) applying it to your local clone,
3) building Git for Windows and verify that it works as expected,
4) report back here.
