Here is the patch reduced to absolute minimum, both functionally and
textually. I removed even 'all', as it has its own subtleties that need
further discussion, so the patch only introduces --diff-merges=off.
If it looks OK, I'll do documentation and tests parts.
Thanks,

Subject: [PATCH RFC v2] revision: change "--diff-merges" option to require
parameter
--diff-merges=off is the only accepted form for now, a synonym for
--no-diff-merges.
This patch is a preparation for adding more values, as well as supporting
--diff-merges=<parent>, where <parent> is single parent number to output diff
against.
