Parser: a line starting with # that is not a comment is prose

startsNewConstruct treated any #-prefixed line as a new construct, so a
line such as "#12 fixed this", which no branch above claims, ended the
paragraph before it was consumed and parse looped forever. Only #+
keywords and comments (# or "# ") start a construct now, and a
paragraph always takes its first line.
