Meh. I haven't particularly been following the thread, but this commit
message doesn't necessarily provide sufficient justification for
further bloating git-format-patch's set of options, its documentation,
and implementation, not to mention potential user-brain overload. With
the possible exception of a 1-patch series, anyone who stores multiple
versions of a patch series without using -o and/or -v is going to have
a mess to deal with regardless of this new option. (Just trying to
figure out which *.patch file belongs to which version of a patch
series will be a nightmare without use of -o and/or -v.)
