Re: [PATCH v3 3/3] diff --submodule=diff: Don't print failure message twice

[David Turner <novalis@xxxxxxxxxxx>]

I keep seeing these as "will merge to next?" in the "what's cooking"
emails.  But I don't see any direct replies, and they don't seem to be
merged.  Is there something I need to do to get these merged?

Thanks.
