Are not the opt_*.h files produced by "defopt file OPTION" always
created?  If so then is it necessary to run "make depend" after every
config?  I would expect that a "make depend" should only be necessary if
new sources are added to the Makefile, and if indeed all the opt_*.h
files always exist then a "make depend" should not be necessary when
only changing their contents (and of course their contents will only
change if an option they contain was changed).

It would be nice if options(4) mentioned which options were defopt'ed
and suggested hint about ``make depend'' in whichever way is correct.
Should I send-pr this suggestion to act as a reminder?  ;-)
