[PATCH] D28548: Improve include fixer's ranking by taking the paths into account.

[David Blaikie via cfe-commits]

Looks like Ben signed off on this on Phab - but the email didn't go to the
list (making this look like code was sent for review, then committed,
without review/approval happening)

Ben: I think Phab doesn't send mail for an approval with no text, so at
least as a workaround you can write something in the comments section when
approving (people often write "LGTM" or similar) to ensure the approval is
reflected on the mailing list.
