git repo back to previous state

[Ralf Wildenhues]

Hello,

thanks to the creators of git and to the administrators of savannah!,
the restoration of the Automake repository was little more work than

  git push --dry-run origin \
           ad-parallel-tests branch-1-10 branch-1.11 master
  # inspect output
  git push origin \
           ad-parallel-tests branch-1-10 branch-1.11 master
  git push --dry-run --tags
  # inspect output
  git push --tags

and has been done now.  Note that I did not use --all, that would have
exposed a bunch of unfinished topics and broken patches.

Cheers,
Ralf
