This patch to Document/bnd makes the Javascript writeln() function
work as well as write(). This version inserts "\n", which seems
to be what the language requires. <br> was wrong.
It duplicates code from write(), but I'm really not keen on Daniel's
alternative suggestion. Sorry. (Re. the earlier thread: I think
it pays a third price, that of being less clear than duplicating
code.)
Hope this helps.
