>>>>>> note that git commit -m A --allow-empty DOES NOT create a commit

Note that git commit -m A --allow-empty *DID* create a commit. Only, that
it received the same name (SHA1) as the commit you created before it
because it had the exact same contents (files, parents, author, committer,
and timestamps). Obviously, your script was executed sufficiently fast
that the two commits happend in the same second.
