> 4. $!               beginning of executable file

3 should only appear in .elc files and the mode used in .elc files
(emacs-lisp-byte-code-mode) already sets up syntax-propertize-function
to handle them correctly.

I don't know what 4 is.  Or do you mean "#!" as the first two chars of
the file?  We could setup syntax-propertize-function to mark them as
comments, indeed.
