To bring the tree clean, I issued "git commit -a -m 'cvs sync'", and
"git-whatchanged -p" shows the most recent commit with the diff actually
*backed out* the most recent change in CVS, and the next change down was
actually the good one.  Weird.  Do I need to start all over again?

So the commit ID reported before the command says Done. was
actually what you wanted, but that latest tree was not checked
out cvsimport, so "git status" reported "you have these changes"
(it should have said "you have these backed-out", but there is
no way for it to know), and obviously your commit on top of that
is to back it out.

I just tried it on a copy of my day-job CVS repository.  Indeed
what it does seem quite strange.

It updated the 'master' branch head, it reported the tip commit
ID before saying DONE, and that commit ID is stored in
refs/heads/master.  However, it does not seem to touch index nor
working tree files (I did not get "you may need to do merge"
message, by the way).

Since I know I was just trying things out, I do not care what is
in my index nor in the working tree files, so I could at this
point say:

	$ git reset --hard

to sync the master tree, but in general you may be running
cvsimport into a dirty tree, in which case you are screwed.

I think reverting this commit would help, but I do not remember
offhand what the breakage this patch was trying to fix.

        cvsimport: Remove master-updating code

        The code which tried to update the master branch was somewhat broken.
        => People should do that manually, with "git merge".

... Ugh, and after I wrote all of the above, the version of git
I have at work predates that commit X-<.  So maybe this was
fixed with that commit, and you are expected to say:

	$ git pull . origin

assuming that you are on "master" branch and cvsimoprt tracks
CVS head with "origin" branch, that is.

Smurf, help?
