(* this outputs an inference rule in one go.  You pass it the list of
   assumptions, then the middle line info, then the conclusion (which
   is allowed to span multiple lines).

   In each case, the int is the number of spaces before the start of
   the line's text and the string is the text of the line with the
   leading trailing space trimmed.  For the middle rule, you can
   also optionally provide a name.

   We need the space info so that in modes where we aren't doing
   something smart we can just format the rule verbatim like the user did
