Markdown Extra Spec: Parsing Section

[John MacFarlane]

Michel,

I think there's a problem with:


> refname

> 

>     A run of one or more characters, excluding any newline and U+005D

> Closing Square Bracket.


This doesn't allow refnames with embedded brackets.  But PHP Markdown
allows

    [[hi]](/url)

as a valid link.  Also, PHP Markdown currently allows embedded newlines,
which are excluded by your definition:

    [hi
    there](/url)

Of course, embedded *blank* lines should be excluded.
