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.
