While attempting to implement the ideas exchange. I found this
note in util.c(util_expand_msglist) from Jakob:

 else if (strchr (argv[i], '[') != NULL)
        {
          /* attachments - GNU extension */
          /*
           * This is a general extension to the msglist format. Basicallay,
           * it adds C-like array subscripting to msg numbers to allow access
           * to just a single part of a MIME multipart message. I.e.:
           * print 7[1],8[1-2]
           * should print the first attachment of message 7 and the first
           * and second attachments of message 8. The format inside the
           * brackets is the same as a msglist, so we should be able to
           * reuse this function for its expansion. This will primarily
           * be used by the new decode command, which needs discussion on
           * the mailing list to nail its syntax down (should it default to
           * saving to a file, printing to stdout, or piping?)
           * -- sparky
           */
        }
      else

It is a good idea but to be able to do this the way msglist is expand
will have to be change to return a structure:

struct {
 int msgno;
 int partno;
}

Comments?
