DESCRIPTION
-----------
--unset-all::
Remove all matching lines from .git/config.
+-l, --list::
+ List all variables set in .git/config.

EXAMPLE
-------
-l::
Cause the logical variables to be listed. In addition, all the
variables of the git configuration file .git/config are listed
- as well.
+ as well. (However, the configuration variables listing functionality
+ is deprecated in favor of `git-repo-config -l`.)
