i've long thought that it wasn't possible for a user's local
configuration to "mask out" a display method configured in
/etc/mhn.defaults. it turns out that this isn't true, but i can't
find any mention of the mechanism in the docs. (my particular desire
has always been to locally disable the rendering of text/html parts,
to force display of the plain parts.)
so i'd like to apply this (or a similar) patch to all of the
appropriate man pages (i.e., mhbuild, mhshow, mhstore, mhn, mhfixmsg),
but obviously only if people think the behavior is intentional.
thoughts? am i the last MH user to realize this is possible?
