Subject: [PATCH] Stop pre-parsing declarations on {} blocks only when nested
 allowed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When nesting is not allowed, we should consume tokens until we meet a
semicolon. When it’s allowed, we have to stop at {} blocks to keep possibly
valid declarations after them.
