Partial merge of man page cleanups from NetBSD:

  revision 1.91
  Fri Nov 7 01:01:46 2003 UTC by lukem

  Add some subsections in the VARIABLE ASSIGNMENTS section.

  In the "modifier description" list, show each modifier with the leading `:'.
  Rationale: it's hard to search for modifiers without it, and we already do
  the same thing in the -options and .makecommands lists.  I now find it much
  easier to find the description for a modifier in the man page.
