The ref@{} syntax will give you ref*log* times, which is probably not
what you want.
I think --since to "rev-list" combined with e.g. "shortlog" is what you
want here, e.g. on git.git:
$ git -P shortlog --since=2.weeks.ago -sn origin/master

Maybe there's a way to get it to spew that out without the numeric
summary, but I can't recall one offhand. I.e. you'd still need awk/cut,
but at least not uniq anymore..
