o Corrected doc entry that stated TOC control macros can be entered

  anywhere in a file prior to invoking TOC (TOC control macros must
  come before START).

o Removed spurious .nop from .ie \\n[#PRE_COLLATE]=1 clause in
  FAMILY (fixes bug that was causing page numbers on pages before
  COLLATE or TOC to be printed too low).

o Added a test at top of COLLATE to set register #NO_BREAK to 1
  if the distance to the next trap is less than one linespace; used
  in NEWPAGE to determine whether to do a 'br or .br. (fixes BUG
  that was causing COLLATE, NEWPAGE, and TOC to spit out a blank
  page when the last line of text before them happened to fall on
  the last legal baseline of the page).

o Changed pad marker used to format TOC entries to permit use of
  the pound/number sign (#) in head elements.

o New macro, PREFIX_CHAPTER_NUMBER, to allow users to prepend
  chapter numbers to the numbering scheme used in head element
  numbering.

o Added missing periods at the ends of head, subhead, parahead
  numbers.

o CHAPTER, with a numeric argument, can now be used to identify any
  document as a "chapter" for the purposes of prefixing the
  argument to CHAPTER to the numbering scheme of head elements.

o Fixed alignment of TOC entries.

o Removed .rr #DOC_HEADER and replaced with

    .if \\n[#DOC_HEADER]=1 \{ .nr #DOC_HEADER 2 \}

  near the end of START.  I.e., #DOC_HEADER becomes "2"  if
  docheaders were on in the previous document.  COLLATE tests for 2
  in order to reset #DOC_HEADER to 1 for use in the user-invoked START
  that comes after a COLLATE.

o Added register, #CHAPTER_CALLED, to CHAPTER; tested for in
  PREFIX_CHAPTER_NUMBER to determine whether the argument to CHAPTER
  can be used to establish a chapter number for chapter number
  prefixes in head element numbering.

o Fixed bug that was causing shifted lists, when returned to, to
  revert to the left margin instead of observing the correct
  indent+shift for the list.

o Added a check in LIST so that if user invokes LIST with RETURN,
  mom doesn't get confused by the initial `R' (which she was using
  to check if the arg to LIST was ROMAN or roman).

o Replaced an incorrectly copied code block in SUBHEAD that was
  preventing SUBHEAD from processing subheads properly when
  PARA_SPACE was on.

o trivial corrections to docs
