[Nmh-workers] mhshow(1) Suggests moreproc can be used.

[Ralph Corderoy]

Hi,

mhshow(1):

    If a display string is not found, mhshow has several default values:

        mhshow-show-text/plain: %pmoreproc '%F'
        mhshow-show-message/rfc822: %pshow -file '%F'

That suggests to this reader that one can use `moreproc' in one's own
entries, perhaps anywhere in the command but certainly at the beginning.
It doesn't seem to be the case.  Does the man page need clarifying?

Cheers, Ralph.
