Well, I think next step would be to replace all those calls with
Git.pm `command`, `command_oneline` and `config``which take an array
of arguments after the "command". In the preview tool we use those but
I don't know if we will find the time to clean that up too in
git-remote-mediawiki :) .
Don't know though if it's better to mix that with this serie which is
mainly based on what perlcritic returns.
