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.
