Yeah, I agree with the "we now show diffs with true parents"
reasoning, and I like the above code reduction, obviously ;-)

This part of the patch I can 100% agree with ;-)
I do not think command line parser does not allow "log -g
maint..master" so all the "limited" processing the remainder of
get_revision_1() does shouldn't matter.
I however think pathspec will affect simplify_commit() and suspect
that "git log -g -20 HEAD path" will behave differently. Perhaps
the difference is "it used to use path in an unexplainable way, now
it ignores", in which case this is an improvement.
Thanks.
