pascal-comment-area
pascal-comment-area is an interactive compiled Lisp function in `pascal.el
'.
(pascal-comment-area START END)
Put the region into a Pascal comment.
The comments that are in this area are "deformed":
`*)' becomes `!(*' and `}' becomes `!{'.
These deformed comments are returned to normal if you use
C-c C-u to undo the commenting.
The commented area starts with `pascal-exclude-str-start', and ends
with `pascal-exclude-str-end'. But if you change these variables,
C-c C-u won't recognize the comments.
