I just ran

    strace -fe execve -o /tmp/st comp

here, with `w', then `q', at the whatnow and /tmp/st has

    17630 execve("/usr/bin/comp", ["comp"], [/* 61 vars */]) = 0
    17631 execve("/home/ralph/bin/vi", ["vi", "/home/ralph/mail/drafts/40"], 
[/* 66 vars */]) = 0
    17631 execve("/usr/bin/vim", ["vim", "/home/ralph/mail/drafts/40"], [/* 65 
vars */]) = 0
    17631 +++ exited with 0 +++

    17634 execve("/usr/bin/whom", ["whom", "/home/ralph/mail/drafts/40"], [/*

    17634 execve("/usr/lib/nmh/post", ["whom", "-whom", "-library",

whom's -check above comes from my ~/.mh_profile.  The -library looks
like another internal option.
