  Updates to the new SideEffect section (kudos to Greg).

  While working on this, Greg discovered a bug (issue #2154) that prevents
  a SideEffect() file from being used as input to another builder call; it
  makes the builder target not get build when run in paralle (e.g. -j2)...
  :-(  So this patch comments out that section of Greg's section.

  This also contains my usual editing pass.  In this case I changed some
  of the examples and added a bunch of text to try to help clarify some
  things that seemed important.  I also added a closing paragraph warning
  that SideEffect() really shouldn't be used as an alternative to specifying
  multiple target files in a Builder call when a command builds more than
  one file that you care about.
