Shortcode names and attributes are separated by at least one space.

Hmm, I usually like to avoid modifying libraries and instead submitting fixes upstream, but in this case my plugin is using an older version of the SyntaxHighlighter library so I don't think it's a big deal.

I'll test this patch once I fix the laptop that I use for coding and then merge.

Thanks!

@mpgo13 I've copied this into the Automattic fork of the plugin. https://github.com/Automattic/syntaxhighlighter/pull/4
