That worked, too.  Actually
	fold -s -w 72
worked.

With that said, however, the sed is still required because the contents of the
text area contain CR's (0x0d, '\r').  Without translating those to LF's
(0x0a), neither fold nor fmt recognize \r end of line.  So the command becomes:

    echo "${FORM_message}" | sed -e 's/^M/\n/g' | fold -s -w 72

where the "^M" is a single character entered as a Ctrl-V Ctrl-M in vim. (Using
\r does NOT work on the regex side of sed's substitute command.

BTW, I posted the proccgi command wrong earlier.  It should have been:

    eval `proccgi $*`

proccgi does a pretty good job at converting form field names and values to
shell variables.  It works with both POST and GET methods.  Take a look at

    http://www.fpx.de/fp/Software/proccgi.c
    http://nleaudio.com/bnotes/proccgi.c

The latter has been modified to convert '-' in form field names to '_'.

Enjoy,
