[Nmh-workers] pager for mhshow of non-text parts?

[Paul Fox]

i'm getting an unexpected invocation of less when running mhshow on
non-text parts.  i.e., if part 3 is image/jpeg, then

    MHSHOW=/dev/null mhshow -form mhl.null -part 3

gives this process tree:

  mhshow -form mhl.null -part 3
   \_ less
   \_ sh -c xv -geometry =-0+0 '/home/pgf/Mail/mhshowPnswsQ.jpeg' "$@" /bin/sh
       \_ xv -geometry =-0+0 /home/pgf/Mail/mhshowPnswsQ.jpeg

the text that's passed through less is the part separator line:

    part 3     image/jpeg                 20K

it doesn't seem to me that less should be run for non-text parts,
nor should the part separator be displayed when mhshowing a specific
part.  (i suspect the two things are linked, of course.)

in addition, on this particular message i'm getting an unexpected
error after the viewing process (xv) is finished:

    $ MHSHOW=/dev/null mhshow -form mhl.null -part 3 10
    part 3     image/jpeg                 20K
    mhshow: don't know how to display any of the contents
            (content multipart/alternative in message 10, part 1)

(the error message actually goes through less as well.)

mhlist says this for the message:

    $ mhlist -verbose -disposition 10
     msg part  type/subtype              size description
