I do not think consistency in this regard is important.

The content of the diff output already often includes various extra
lines that can be more or less relevant depending on the tool used.
Some of those lines will be on stderr, others on stdout.  Tools that use
patches know to ignore leading and trailing garbage, so I really don't
think it's that important.
