git-gui: Replace \ with \\ when showing paths.
We already replace \n with \\n so that Tk widgets don't start a new display line with part of a file path which is just unlucky enough to contain an LF. But then its confusing to read a path whose name actually contains \n as literal characters. Escaping \ to \\ would make that case display as \\n, clarifying the output. Signed-off-by: Shawn O.
