Nicholas Nethercote d5370d981f Remove bra/ket naming.
This is a naming convention used in a handful of spots in the parser for
delimiters. It confused me when I first saw it a long time ago, and I've
never liked it. A web search says "Bra-ket notation" exists in linear
algebra but the terminology has zero prior use in a programming context,
as far as I can tell.

This commit changes it to `open`/`close`, which is consistent with the
rest of the compiler.
