Fenced code blocks attributes in curly braces break highlighting

[sbaack]

Thanks for this package. This issue is similar to #123. I usually add fenced code blocks attributes in curly braces, as in {.bib}. This breaks highlighting in language-markdown (gfm works fine):

Removing the curly braces fixes the issue:

I don't insist on using curly braces, it's just that I used to do it this way and I have a lot of older documents which I would have to readjust when I want to keep using language-markdown. Would be glad if this could be fixed.

It definitely seems related to #123. No idea why it's still an issue, will look into it. Could you verify for me if the problem persists if you switch bib to a language that is supported, like js?

[sbaack]

Thanks for the quick reply. This problem persists when I switch to {.js}.

[burodepeper]

And if you switch to {js} without the leading dot?

[sbaack]

Doesn't work either. However, I found that if I remove the closing brace, highlighting works again regardless of the language used. So{.bib, {.js, {js all work, but {js} or {.js} don't.

That could very well be related to #139. {js } might work too. I'll soon have a look at it. I need some good tests to make sure it is truly fixed. Not sure why this keeps slipping through. Thanks for reporting.

You're right, {js } or {.bib } works. Thanks for your work!
