Support for extracting configuration from different files

Browse source

of .git/config if set. Also add $GIT_CONFIG_LOCAL as a
forward-compatibility cue for whenever we will finally come to support]
global configuration files (properly).

GIT_CONFIG::
Take the configuration from the given file instead of .git/config.

Currently the same as $GIT_CONFIG; when Git will support global
configuration files, this will cause it to take the configuration
from the global configuration file in addition to the given file.
