Added spell-ignore and spell-end-ignore about several regions where

spell checking doesn't make sense.  Removed rcsid line.  Added ispell
magic after @bye.  Several spelling errors fixed.
(daemon, badspell): New macros.  Use them where appropriate.
(holl): New macro.  Change all examples of Hollerith-coded strings
	to use this.
(re-z-lookup): Fixed broken length of Hollerith string in the example.
