Obviously the manpages-dev package should not have shipped these files
as long as there are in glibc-doc; this is tracked in #1068166.

Considering that the manpages in glibc-doc are not included upstream and
created via a Debian patch, that makes a lot of sense. I was not aware
of that fact.

Adding a Breaks on glibc-doc (<= 2.38-6) to manpages-dev is no good,
because that version is only in experimental and will remain there for
several weeks if not months. I think manpages-dev should drop these
files for now and re-include either when glibc 2.38 is in unstable or
when it is in testing.
There is also the problem that some derivatives (most notably Ubuntu)
are already shipping glibc 2.39 and will have to adjust Breaks/Replaces
versions in manpages-dev accordingly. Thoughts?
Cheers,
