From 322bee0aac0f177127e4a33aff94a5fa2158a0f9 Mon Sep 17 00:00:00 2001

Subject: Additional listing options, improve help output, fix macro limits

Additional listing options:

   -Ld to display counts in decimal
   -Lp to output a list file in every pass (to make sure one exists)

Clean up the help output and make it comprehensive. The -hf and -y
options are no longer necessary, although they are supported for
backwards compatiblity.

Fix macro-levels so it actually count descent levels; a new
macro-tokens limit introduced for the actual token limit.

Slightly simplify the limits code.
