Using git rebase (and a lot of patience with the earlier commits, where
there were more conflicts due to the poor commit history chosen by
cvsps/git-cvsimport; the conflicts lessened in later commits, as the CVS
history touched more files), I repaired the damage.  However, in doing so,
I had to force the revision of existing published tags.  This means that
anyone who has already pulled the m4.git repository now has outdated tags;
the best way to repair this is to delete the tags from your repository,
then do a fresh git pull to pick up the updated tags under the same name
but different reference (perhaps followed by a git-gc, since it abandons a
lot of commit objects).  If you are looking at the repaired tree, you will
see the following:

$ git rev-parse m4-1.4{,.1,.2} release-1.4.{3,4,4b,5,6,7,8,8b,9,9b,10}
