The code looks correct, however I think we can improve it.
(Originally I was just wondering if stderr is the right output,
which lead me to the thoughts below:)
Looking through the code of merge-recursive.c,
all the other merge outputs are done via 'output()'
that is able to buffer up the output as well as handles
the output for different verbosity settings.
So I would think we should make the output() function available
outside of merge-recursive.c. (and rename it to a be more concise
and descriptive in the global namespace) and make use of it.
Funnily we already have MERGE_WARNING in submodule.c
which outputs information for all the other cases. I would think
we ought to convert those to the output(), too.
Thanks,
Stefan
