Not for groff.

groff uses the hyphenation patterns from TeX.  You get the same
problem with current TeXLive, using the additional set of US
hyphenation exceptions:

  \input ushyphex
  \showhyphens{backpedaling}
  \showhyphens{backpacking}
  \bye

  -> backpedal-ing
     back-pack-ing

I've CCed Barbara Beeton <address@hidden>; she is maintaining the
hyphenation exceptions list.  Please send your other findings to her
also.
