Fixes in 1998 html files

This includes some notices to those who wish for a greater challenge.

In the 1998/schweikh3 the man page (and its copy to demonstrate the
entry) have been updated slightly but only in comment (move 'or' from
the command suggested to render it in text to its own line before the
next command also in comment).

The bugs file was updated for an entry or two.
