Modified the rules for vendor ids:

- explictly say not to edit infrastructure for vendor ids (not just the
  ids).
- say to enclose vendor ids and their infrastucture in ``#if 0'', and
  partly explain why.
- don't set a bad example by mangling the Berkeley id infrastructure from
  ``static char sccsid[] ...'' to ``__RCSID(...)''.
- show a blank line between the vendor id cruft and the FreeeBSD if cruft
  in the example.
- relaxed the rule about adding "From: " to say that "From: " is actually
  useful if the file has been renamed.
- minor English improvements.
