Hi Doug,

> Does it make more difference in other macro packages?

Yes, particularly those with more comments, than -ms say, and with
.while loops, like -mom, apparently.  `info groff | less' says

    * The body of a 'while' request is treated like the body of a
      'de' request: 'gtroff' temporarily stores it in a macro that
      is deleted after the loop has been exited.  It can
      considerably slow down a macro if the body of the 'while'
      request (within the macro) is large.  Each time the macro is
      executed, the 'while' body is parsed and stored again as a
      temporary macro.

Cheers, Ralph.
