Re: [PATCH] git-gui: fix file name handling with non-empty prefix

> Commit e3d06ca (git-gui: Detect full path when parsing arguments -
> 2012-10-02) fixed the handling of absolute paths passed to the browser
> and blame subcommands by checking whether the file exists without the
> prefix before prepending the prefix and checking again.  Since we have
> chdir'd to the top level of the working tree before doing this, this
> does not work if a file with the same name exists in a subdirectory and
> at the top level (for example Makefile in git.git's t/ directory).

> Instead of doing this, revert that patch and fix absolute path issue by

> correctly handle absolute paths by skipping the prefix in that case.
