Not by me, at any rate.

Perhaps, but it isn't.

The problem with that is that it's not there in the first place:

   $ grep par ~/.mh_profile
   $ echo $?
   1

In fact,

   $ grep mhbuild ~/.mh_profile
   mhbuild:        -maxunencoded 500

   $ grep html ~/.mh_profile
   #: mhshow-show-text/html:       %pmime_helper %F %s %{name}
   mhshow-show-text/html:       html_to_text %F | cat -s
   mhshow_in_browser-show-text/html:  %pmime_helper %F %s "%{name}"
   mhfixmsg-format-text/html:      html_to_text < '%F'

   $ grep -w par ~/bin/html_to_text
   $ echo $?
   1

I'll append the full text of the script in case you'd like to see it, but
I'm pretty sure it's not implicated here.

In fact there are no invocations of par anywhere in my ~/bin directory; the
only occurrences of the word are in some old data files:

   $ grep -lrisw par ~/bin
   /home/smw/bin/mars/reports/data/FMARS/jrn/text/20070729
   /home/smw/bin/mars/reports/data/FMARS/jrn/text/20070718
   /home/smw/bin/mars/reports/data/FMARS/jrn/text/20070719
   /home/smw/bin/mars/reports/data/FMARS/jrn/raw/20070719

...and these files have nothing to do with nmh in any way.

I'm reminded of an old Jackie Mason routine, in which he describes a visit
to a psychiatrist.  After a fair bit of dialog which I won't repeat here,
this snippet occurs:

   psychiatrist:  I see your problem.  You hate your sister.

   Jackie Mason:  I haven't got a sister.

   psychiatrist:  I can't help you if you won't cooperate.

...so I feel a need to apologize for being uncooperative :-/, but I'm at a
loss here.

#
#  Steven Winikoff
#  2010/04/28
#
#  note:  this script uses links
#         [ http://atrey.karlin.mff.cuni.cz/~clock/twibright/links ]
#         because it seems to be the only program available which
#         renders tables reasonably
# 
#         alternatives (lynx and vilistextum) both show tables one
#         column at a time instead of row by row!
#
#
#         UPDATE, 2018/08/22:
#
#         switched from links to elinks, because links fails when invoked
#         via procmail if the source HTML code contains invalid characters
#         (as in a file in Windows character encoding which isn't labelled
#         as such) -- the symptom is that a properly structured message
#         will be converted into one which has an empty HTML part, which
#         is a problem if (and only if :-) the HTML part needs to be viewed
#         in a graphical browser (see ~smw/bin/view_html_message, as called
