I was playing with Markdown (yeah I'm that kind of nerd) and I ran into the following bugs:

This message is also on pastie in case the list strips tabs: http://pastie.textmate.org/private/tetzlcuww7rmb8jkcff4ia

- - -

This text is indented from the bracket ">" by one tab (which is allowed in Markdown) and is mis-highlighted by TextMate as a nested code block. If, however, I indent by 4 spaces TextMate highlights this correctly.

When blockquote-nested code blocks, like this paragraph, are  

processed into HTML they include two spaces at the beginning of the code block.

* Code blocks in lists must also be indented by 2 tabs.

This should be highlighted as code. Processing this to HTML works as expected, and does not include the blockquote's "2 space" bug.

[Links](http://example.com) can be [written][foo] a number of [different ways][bar].

[foo]: http://example.com "This line begins with 2 tabs. It is highlighted as code, but processes as a title (as it should)"

[bar]: http://example.com 'single quoted titles don't highlight or process, but should be allowed according to the Markdown syntax'

Is there a specific reason single-quote titles aren't allowed?

Also, shouldn't links like this http://example.com be scoped as `string.other.link.markdown` or something so that they highlight like every other kind of link?

Thanks for indulging me.
