  * wibbles to encourage HsColour to lex nested comments correctly
  It seems that the standard Prelude.lex function does not do
  nested comments well, so something like {- :-} causes things
  to fail.  Workaround is just to separate the comment more clearly.

    M ./src/Text/XML/HaXml/DtdToHaskell/Convert.hs -5 +5
