I think if there's an exact pattern "depth" match, then
git history should be searched by that subdirectory.

So for example:
	F:	drivers/scsi/megaraid/

A lookup for drivers/scsi/megaraid/mega_common.h (same depth,
search all commits in drivers/scsi/megaraid) now shows:

$ ./scripts/get_maintainer.pl -f drivers/scsi/megaraid/mega_common.h  --rolestats --git
Neela Syam Kolli <megaraidlinux@....com> (maintainer:MEGARAID SCSI DRI...)
"James E.J. Bottomley" <James.Bottomley@...e.de> (maintainer:SCSI SUBSYSTEM,commit_signer:20/27=74%)
linux-scsi@...r.kernel.org (open list:MEGARAID SCSI DRI...)
linux-kernel@...r.kernel.org (open list)

A fair bit with all public discussions.

It's been shipped more or less that way since 2.6.30
beginning in April, 2009.

I get annoyed when people suggest that the maintainer
of that silly script isn't responsive.
