-The 'fast' in the above 'git resolve' is not a magic. I knew this
-'resolve' would result in a fast forward merge, and if not, there is
-something very wrong (so I would do 'git reset' on the 'master' branch
-and examine the situation). When a fast forward merge is done, the
-message parameter to 'git resolve' is discarded, because no new commit
-is created. You could have said 'junk' or 'nothing' there as well.

There is no need to redo the test at this point. We fast forwarded
and we know 'master' matches 'revert-c99' exactly. In fact:
nor tag anymore, so remove them:

-$ rm -f .git/refs/tags/pu-anchor .git/refs/heads/revert-c99
+$ rm -f .git/refs/tags/pu-anchor
+$ git branch -d revert-c99

It was an emergency fix, so we might as well merge it into the
