Fair enough.  The alternative is for packagers to install them, like
they do for recovery.conf.sample.  I'll update the patch as soon as we
get consensus that this is wanted.

I was imagining just using the "include" directive.  I have heard the
desire for annotated sample conf files for the contrib modules twice now
from different people which is why I wrote the patch.  If we decide that
the extra documentation is too much of a burden, I can understand that,
