Is there a way to do (or request enhancement or fix bug):
   1) Can I pipe a UN*X command into a Mush variable? This is so I can do
      something like this in my .mushrc:
         expr '${COLUMNS:-80}' - 54 | set subject_len
         set hdr_format = "%22n %M%-02N %T (%-3.5lL)%.${subject_len}s"
         ...or...
         set subject_len = "`expr '${COLUMNS:-80}' - 54`"
         set hdr_format = "%22n %M%-02N %T (%-3.5lL)%.${subject_len}s"
   
   2) With the above hdr_format, the "%n" field will substitute
      something like "TO: addressee" if mush recognizes me as the sender.
      It looks like is only looking at the username field of an address
      that looks like "other_site!scott" and comparing with my username.
      Seems it should look at the user's machine name (the alts command
      list), too. Am I missing a variable setting somewhere or is it
      supposed to work this way?
   
   3) Is there some way to have the curses mode "update" command go
      ahead and update the folder without asking?

Thanx,
