Whoops.

It's pretty benign: Doug will still only get a single email.


checkpatch checks for duplicates cc's but I think it assumes that
things like

Reported-by: fred
Tested-by: fred

were intentional.

It would perhaps be better for checkpatch to special-case the "Cc:
fred" tag and report a duplicated Cc: if fred was also mentioned in any
other tag.
