I did not even bother looking at them.  You'll probably tear your hairs
out, but I lean towards scrapping the comments mostly, and instead
augment the title texts to things like
"Incorrect title (from book)"
"Correct title (from bookpart)"
and similar.  That way, it is easier to see whether the results are as
expected.

Description:
Issue 1650: merge multiple header specifications.

Books get initialized from $defaultheader, this is what toplevel \header
will set, and scores and bookparts are initialized empty so that they
will end up combined with their respective (possibly implicit) books.
