Use of uninitialized value in git-remote-mediawiki

[lumeng]

I have the latest git-mediawiki software from the master branch of the official git repo (git://git.kernel.org/pub/scm/git/git.git). When I git push, there are some new errors about git/2.13.3/libexec/git-core/git-remote-mediawiki:

$ git --version
git version 2.13.3
$ git push
Last local mediawiki revision found is 5768.

is this just a cosmetic problem? or is there something actually not working here?

could you detail the exact configuration you are using? (which git version, git config -l, etc).
