Subject: [PATCH] Add a "checkpatch" target that does a "patch -C" instead of a
 "patch". Note that the two "touch"s I took out from do-patch shouldn't have
 been there in the first place.

This target may give incorrent results if two separate patches deal
with the same file, and their hunks overlap.  (But having those kinds
of patches are bad, and they should be merged anyway.)
