  24 @command{fmt} prefers breaking lines at the end of a sentence, and tries to
  25 avoid line breaks after the first word of a sentence or before the last word
  26 of a sentence.  A @dfn{sentence break} is defined as either the end of a
  27 paragraph or a word ending in any of @samp{.?!}, followed by two spaces or end
  28 of line, ignoring any intervening parentheses or quotes.  Like @TeX{},
  29 @command{fmt} reads entire ''paragraphs'' before choosing line breaks; the
  30 algorithm is a variant of that given by
  31 Donald E. Knuth and Michael F. Plass
  32 in ''Breaking Paragraphs Into Lines'',
