Yes, most of the time you'll want to run it as `b4 shazam -Ms`.

Unfortunately, `shazam -M` is not perfect, because we do need to know the
base-commit, and there's still way too many series sent without this info. We
do some magic trying to figure out where the series might belong (basically,
by comparing blob hashes and trying to find the tree with the same set of blob
hashes as in the patch), but it only works if you have the same local repo as
the contributor.
