With this function you can hyphenate a text so that words are
sensibly divided at overlong line ends, provided you have loaded a
hyphenation dictionary. This is needed when you have not set up
automatic hyphenation (see Hyphenation options
function below),
perhaps because it takes too long. To use it a text frame must be
selected or a text block marked. If a frame is active, then after a
safety query all other text frames in its piping chain will be
hyphenated too.
