git-config: handle --file option with relative pathname properly

Browse Source 
When calling git-config not from the top level directory of a repository,
it changes directory before trying to open the config file specified
through the --file option, which then fails if the config file was
specified by a relative pathname.  This patch adjusts the pathname to
the config file if applicable.

The problem was noticed by Joey Hess, reported through
 http://bugs.debian.org/445208
