[svn] * Makefile.in (sample.wgetrc.munged_for_texi_inclusion): Added build,
  dependencies, and distclean cleanup of this new file.

* sample.wgetrc: Uncommented waitretry and set it to 10, clarified some wording,
  and re-wrapped some text to 71 columns due to @sample indentation in
  wget.texi.

* wget.texi: Herold further expounded on the behavior of waitretry -- reworded
  docs again.  Changed note saying _all_ lines in sample.wgetrc are commented
  out.  Don't have an entire hand- cut-and-pasted copy of sample.wgetrc in this
  file -- use @include.
