If the world was built using either -DNOCLEAN or -DNOCLEANDIR, it was
possible to use old generated doc-* files as the source for new ones.
Wrong -mdoc files would then be installed, and man(1) failed with the
following diagnostics:

mdoc error: end-macro (.em) respecification is not allowed. (#41)
            Should this have been `.Em ...'?

Put helper stuff into `beforedepend' to cleanup old files.

Makefile first infected in rev 1.15.
