[PATCH] git-gui: Prevent double UTF-8 conversion

["Łukasz Stelmach" <l.stelmach@samsung.com>]

Set encoding to utf-8 for file descriptors used to receive data from
git commands.

With encoding on the file descriptor set to "binary" Tcl (8.6 in my case)
does double conversion which breaks e.g. author name in amended commits.

For example "\305\201ukasz" (as written by git cat-file) becomes
"\303\205\302\201ukasz".

So, this is the second attempt to draw some attention to this patch,
since the first one has somewhat failed.
