(pascal-mode-map, pascal-outline-map):

C-c C-b now inserts block.  C-c C-d does goto-defun.
`#' calls on electric-pascal-hash.
(pascal-calculate-indent, pascal-indent-alist)
(electric-pascal-tab, pascal-indent-case):
Better handling of indent within case.  Support for CPP.
The `;' in the last statement of a subblock may be omitted.
(electric-pascal-hash): New function.
