I can't think of any such issues off the top of my head, but I
wouldn't be surprised if there were unknown issues about this.

oh wait, I *do* remember something arises from the translations:
the documentation has multiple copies of the same .ly file in
various translations.  The whole reason we have a out/lybook-db/
is to try to notice idential filenames and avoid rewriting them.
A few years ago (sorry... between 2 and 5 years is as much as I
can narrow it down from memory, and a few quick searches of -devel
didn't pinpoint anything) that was a serious problem with doc
compiles.

actually, a quick look at the history for make/lydocs-make
suggests
3a9c1df02fdb6846418c5794a7b04d07209e95b3
and I definitely remember that John Mandereau was working on this
stuff.  It would fit the time span.
