I'll blame you for that one, since this output comes from your
'git print-patch's script, which only prints out the From: and Subject:
headers. ;-)

Yeah, I wouldn't be sad to see this get moved to the trace2 mechanism.
In fact, I almost prefer that approach, since server operators and
developers can still debug the bitmap machinery, but end-users of forges
like GitHub won't see the output.
Maybe that is the best approach forward. Teng Long: does that sound OK
to you?

Yeah, I had always thought that it was odd that we had to go through all
of the repository's possible bitmaps and try to open them one by one. It
might be interesting to have a file that lists the path of _the_
bitmap, which we consult first and then try and open that pack or MIDX
bitmap. But I dunno.

I agree, they end up the same in either approach you take.
Thanks,
