m4/groff.m4: Recast help strings.

* m4/groff.m4 (GROFF_URW_FONTS_PATH, GROFF_WITH_COMPATIBILITY_WRAPPERS,
  GROFF_APPDEFDIR_OPTION, GROFF_UCHARDET): Recast help strings to more
  closely parallel structure any style of Autoconf's own help strings.

  (GROFF_WITH_COMPATIBILITY_WRAPPERS): Recast to tighten wording.
