[texhax] Hypenation of web names

[Michael Barr]

The following (plain tex) file illustrates one solution.  Note that it 
does not permit hyphenation before a period, which would be a disaster:

\catcode`\.=\active
\def.{\char46\allowbreak}
This is the time for all good men to come to the aid of the party
script.aculo.us.script.aculo.us.script.aculo.us.script.aculo.us.script.aculo.us.script.aculo.us.script.aculo.us.script.aculo.us.script.aculo.us.
  \bye
