Description of problem:
If I put the following line in /etc/nmh/nmh.defaults:

 mhshow-show-text/html: %plynx -dump -localhost -force_html -noredir '%F' | less

it is ignored and html messages are shown as raw html. But if I put that same line in my ~/.mh_profile, lynx is called and renders the html. I know that the settings in mhn.defaults aren't all being ignored by mhshow, since whether I have

 mhshow-charset-iso-8859-1: %s

there makes a difference when reading messages with that charset.

Version-Release number of selected component (if applicable):
nmh-1.1-8-fc4

How reproducible:
Always

Steps to Reproduce:
1. Get a message which has Content-type: text/html.
2. mhshow

Actual Results:  mhshow displays a bunch of raw html.

Expected Results:  mhshow should call lynx to render the html.
