What do you think? I still wish I could come up with the usual backward compatibility transition dance for this case, but I do not think there is one. However. If "-m" were doing a more useful thing than "compare with each parent separately", people may have aliased "log -m" to something so that their "git aliased-log" and "git aliased-log -p" would work better for them than "git log" and "git log -p", but quite honestly, I do not think "git log -m -p" output is readable by humans (after all, that is why we invented -c and --cc), so the population that get hit by this incompatible change may be very tiny minority in relative terms.
