I think you can extend a lot less. Or even not at all. Just look at
the previous line:
- if it's empty, you're at the beginning of a paragraph and you set the
`syntax-table` property of the current line's first char according to
whether it's a ;([# or something else.
- If the previous line is not empty, just copy the `syntax-table`
property you find on the first char of the previous line.
Stefan
