[Nmh-workers] mhshow with subparts?

[David Levine]

On the attached message, this command:

  mhshow -part 1.1 -form mhl.null

produces no output.  mhlist shows a part 1.1:

 msg part  type/subtype              size description                         
1231       multipart/mixed            276
     1     multipart/related          107
     1.1   text/plain                  29

"mhstore -part 1.1" properly stores it.  The difference in
behavior is caused by a different value for the second
argument, sP, in calls to part_ok:

  uip/mhlistsbr.c:317:  if (part_ok (p, 1) && type_ok (p, 1))
  uip/mhshowsbr.c:747:  if (part_ok (p, 0) && type_ok (p, 0)) {
  uip/mhstoresbr.c:286: if (part_ok (p, 1) && type_ok (p, 1)) {

Analogous behavior happens with -type text/plain.

If I change that 0 second argument to a 1, mhshow displays
the contents of part 1.1, as I expect.  Does anyone know why
mhshow passes 0 to part_ok and type_ok?  It prevents mhshow
from doing what I want with multipart messages but there
must be a reason.  Here's the code in part_ok that uses sP:

  if (npart == 0 || (ct->c_type == CT_MULTIPART && (sP || ct->c_subtype)))
      return 1;

Thanks,
David
