24@command{fmt} prefers breaking lines at the end of a sentence, and tries to
25avoid line breaks after the first word of a sentence or before the last word
26of a sentence.  A @dfn{sentence break} is defined as either the end of a
27paragraph or a word ending in any of @samp{.?!}, followed by two spaces or end
28of line, ignoring any intervening parentheses or quotes.  Like @TeX{},
29@command{fmt} reads entire ''paragraphs'' before choosing line breaks; the
