I have an alias that takes two arguments and compares their patch IDs.
I would like to use to make sure I've tested exactly what I submit
(patch by patch), like

   git patch-cmp origin/master.. file-being-sent

However, I cannot do that because git patch-id is fooled by the "-- "
trailer that git format-patch puts, or likely by the MIME boundary.

This patch adds hunk parsing logic to git patch-id in order to detect an
out of place "-" line and split the patch when it comes.  In addition,
commit ids in the "From " lines are considered and printed in the output.
