As I read the mhshow man page, that variable designates a file which is
additive to, not alternative to ~/.mh_profile. Indeed,
MHSHOW=/dev/null mhshow
seems to be the same as mhshow. So if there is a text/html
content type handler in ~/.mh_profile, I would have to somehow cancel it.
How would I do that?
I had to experiment a little bit for this; it turns out a profile entry in
specified in MHSHOW overrides things in mhn.defaults, but NOT things in
your .mh_profile. Which seems counter-intuitive to me, but whatever.
i added this paragraph to mh-profile.man a while ago to try and clear
this up, but i see that i didn't mention the ordering issue, which i
agree is unexpected. this paragraph is cumbersome -- perhaps someone
can help simplify it? (there are pointers to this section in all the
relevant mhbuild/mhshow/mhstore man pages as well.)
Profile Lookup
Some nmh programs will look in more than just the user's .mh_profile
for profile entries. In particular, mhbuild, mhshow, mhstore, and mhn
will also all look in a file specified by a program-specific environ‐
ment variable (see below), and after that in the system-installed pro‐
file (/usr/local/nmh.git/etc/mhn.defaults). (The mhfixmsg program is
similar, but doesn't consult an environment variable.) The first match
found for a particular component will be used, allowing user-supplied
entries to override those that are system-supplied. A profile compo‐
nent with a blank value field will "hide" any later occurrences of the
component, and will make the entry appear to be absent.

Paul's got the right answer; a blank entry of the form:
mhshow-show-text/html:
will do the trick, ASSUMING you don't have anything in your .mh_profile.
