$projectshort is still in the process of being imported. To import
into $projectshort use 'git push --exec=import'. If you are done
importing, do:

   ssh $USER@git.gnome.org finish-import $projectshort

$projectshort is no longer in the process of being imported. You
can push to $projectshort normally. If you accidentally ran
finish-import too early, please contact gitmaster@gnome.org
for assistance.
