Matches in a grammar (and in bundle items in general*) can only target a single line, no multi-line matches. This is done for performance reasons as if you could target multiple lines it would require significant re-parsing with every keystroke. This is the reason you see the slightly odd scoping of the ‘setext’ style headers.

Was there ever a multiline version of the parser that I could check out and play with?
