Indeed, I even extended the syntax-table facility so as to be able to
properly support the many different comment styles in Pascal.

I installed the patch below, which should do what you asked for.

I hope someone can try and merge delphi.el and pascal.el.  It can be
done step by step, e.g. by first making delphi.el a derived mode of
pascal.el and then moving delphi.el code to pascal.el bit by bit.
