Before this change, a [...] prefix would be removed only as long as
its length did not exceed 2/3 of the subject length.  Now, when the
bracketed quantity starts with PATCH, it is removed unconditionally.
Otherwise, the existing behavior remains unchanged.

Thanks, I think this is a good idea in general, but have two comments.

 - I am not sure how this should play with 17635fc (mailinfo: -b option
   keeps [bracketed] strings that is not a [PATCH] marker, 2009-07-15).

Ah ha!  I see you've already scratched this itch,
and more thoroughly, to boot.  Also, I prefer your
removal of the hard-to-describe 2/3 threshold.

 - Regardless of interaction with 17635fc, Things like [RFC PATCH]
   [SECURITY PATCH] might want a similar treatment.

As your patch does.

I started looking at git-am.sh and spotted what appears to be a typo.
There is only that one use of $keep_subject, so its value currently
comes from the environment.
