don't worry.  You have patches pending for longer, and they didn't end
up in my spam folder (gah, wish I hadn't written that now ;-)

Done.  Welcome aboard!  You should be able to clone from the read-write
URL now, or add that as new (push-able) remote to your existing

Yes it does.  But that is far less of a problem than with, say, CVS.
There are several clones of this repository around from which a botch
could be undone by pushing a non-forward, in the unusual case that
should be necessary.  Of course, such a thing should not be done

Not that I know of.  I've made it a habit to use both
  gitk --all
  git push --dry-run

in order to see what would happen, and if I intend to only change some
branches, I use, e.g.,
  git push --dry-run origin master

and then remove the --dry-run if all looks good.

You shouldn't push non-fast-forwards.  I think the only viable exception
to this should be security-related issues (where you've accidentally
pushed before information that must not be public), but Automake is
unlikely to deal with such.

Now, I guess I will change habits a bit and let you push good patches as
appropriate.  When I write "OK for maint", then that implies that you
may apply the patch on top of maint, and also that you may merge maint
to branch-1.11 and to master whenever maint is not fully merged to them.
Please let's not merge more often than necessary, i.e., it is enough to
do it after a series of related patches, or at the end of a session.

For merging to work reliably, you need the git-merge-changelog program
from gnulib to be installed correctly, and your git repository adjusted
so that it is used for the ChangeLog.  See the documentation of the

Yep, agreed.

Because I'm in general reluctant to remove information about work done
by others in the past.  I think at least the user-dep-gen-branch saw
real development, and was merged to the main tree later (a bit of
information which of course the CVS tree could not preserve), so it can
help when debugging issues that relate to code added then.  Such
information has helped me pinpoint reasons for some code before, even
when the original change was from the last millenium.
