Hmm.  That next paragraph was about the inneer $(srcdir), not
the innder $(distdir).

Ah, yes, I forgot about that.  It has also been a source of
problem in the past.  See for instance PR/390 where a directory
that contains automatically distributed files is EXTRA_DISTed:
during `make distdir', the automatically distributed files are
first copied, and then the recursive copy of the directory fails
because it cannot overwrite the files that have already been
copied.

That sounds fine to me, although it doesn't fix PR/390.  Maybe
we should rather find a way to copy files with the right
permissions?
