[TxMt] Markdown typing pairs

I guess this is a two-part question:

1. Why weren't `<` and `>` included as a smartTypingPair for Markdown? Since those are the characters used to surround in-line URLs that should become clickable links, it seems like it should be there so you could just highlight a URL and type `<`. This seems pretty obvious though, so maybe this pair was omitted intentionally for some reason I haven't caught onto?

2. Since the scope in Markdown includes `text.html`, why doesn't that pair get pulled from the HTML bundle's preferences? Is it because there are explicitly defined pairs for a more specific scope in this case (`text.html.markdown`)?

Just curious. Thanks.
