[PATCH 0/7] Prepare git-remote-helpers series for hg support

This series does not add hg support, but it does do all the refactoring that is needed to make it possible. With this series applied actually adding full-fledged hg support is a matter of adding the git-remote-hg file. The reason the git-remote-hg file is not included in this series is that while I have finished support for 'git clone hg::/path/to/hg' as well as 'git fetch hg::/path/to/hg' and 'git fetch hgremote', currently it does a full export on each run (that is, incremental fetch is not supported). Nevertheless, I think it is vital that this is included in the series before we do anything serious with it. I hope to have the git-remote-hg bit done tomorrow before I get on my airplane, but no promises there.

Junio, I can try to re-roll the entire series after I finish git-remote-hg, or I can just send it in on top of this series.

Based on abdcdc5c [More fixes to the git-remote-cvs...].

Johannes Schindelin (1):
      Finally make remote helper support useful

Sverre Rabbelier (5):
      .gitignore: add git-remote-cvs
      Add notify and warn to util.py
      Allow both url and foreign vcs in remote config
      When updating refs after a fetch, resolve the symref if set
      Factor ref updating out of fetch_with_import
