[PATCH] git-gui: Few issues with using full path name

[Andrew Wong <andrew.kw.w@gmail.com>]

I ran into a file name parsing issue in git-gui. If I'm in a subfolder and try
to pass a full path to "git-gui blame", then "git-gui" will fail to detect the
argument as a valid path. The first patch will handle this scenario.

The second patch just another issue that I noticed when "git-gui" fails to
detect the file name. It'll then try to use the previously detected "head" as
the file name, while prepending it with "prefix". This is incorrect if "head"
is actually a full path.

There is also an issue when using a full path along with a rev argument, but I
don't have time to look it right now. I'll try to get to that issue another
time.
