Nested parenthesis in href breaks inline hyperlinks #45

Closed brandonc closed 13 years ago

A tricky edge case is parenthesis inside inline urls. Sundown and github flavored markdown both seem to stop on the first occurrence of )

[inline hyperlink with a paren](http://www.example.com/test#nav(1)) inline hyperlink with a paren
[reference hyperlink with paren][1] reference hyperlink with paren

Perhaps this can be fixed by counting nested parenthesis?

Hey Brandon,

the Markdown standard defines that any "active" characters that need to retain their literal values must be prefixed with a backslash, i.e. escaped. Parentheses clearly fall under this category.

[the Pogo](http://en.wikipedia.org/wiki/Pogo_\(dance\))

Let's dance the Pogo. Pogo pogo pogo pogo pogo pogo. Note that the first backslash in the opening parenthesis is not required, it's there for completeness.

Cheers!
