Good question!
I believe --diff-merges=all should reset revs->diff back to 0 to
entirely undo all the effects of '-c' and '--cc', provided those
appeared before on the command-line, that '-m' fails to do.
Admittedly, I didn't yet check what is the outcome of, say,
"git log -c -m". Is it = "-c", ="-m", or what?
Also, this makes 'all' not the entire synonym for '-m', and that's why I
removed 'all' from the second version of the patch ;-)

OK, I'll take further look at this for further changes, -- thanks for
telling!
My general approach though is that every of mutually exclusive options
should better explicitly set all the involved variables appropriately.
Thanks,
