Currently the markdown reader's quoted parser ignores curly double and single quotes. This is okay for some kinds of output, but not for others. It would be best to produce a Quoted inline consistently, whether or not curly quotes are used.

Also, the parser should be able to handle the American standard of putting an open quote at the beginning of a paragraph with no close quote, if the same speaker is speaking in the next paragraph.

The first part resolved by 7864f30717767f89ee33532b59819b51ef2e14d4

The second part (open quote with no close quote) dropped on closer consideration. It's a bad idea, because the writers will just put the close quote in.
