git-format-patch builtin isn't using git-cherry?

I used to rely on git-format-patch to be calling git-cherry in the bg,
so that I'd know that the obviously merged patches were upstream
alredy. It doesn't seem to do it any more.

Reading cmd_format_patch() in builtin-log.c, it seems to have lost
that magic that made it so useful... :( Can a kind soul that speaks C
fluently help me out here?

(The new format-patch gives me 180 patches to merge/rebase, where the
old one tells me there's only 51. guess which one I prefer ;-) )

cheers,
