Subject: [GIT GUI PATCH 1/2] git-gui: teach _which procedure to work with absolute paths
Message-ID: <e7a733b5ad4e2009aec205235a95a610ee18947b.1332523097.git.hvoigt@hvoigt.net>
In-Reply-To: <cover.1332523097.git.hvoigt@hvoigt.net>

_which is useful to check whether a certain command can be called.
Previously when given an absolute path it would not recognize it as
an existing program. Lets change that so it transparently handles such
cases.
