Syntax highlight in diff and edit preview broken

[silverwind]

The highlighting code currently assumes a pre > code structure to work but this is not given for diff and edit previews. Given that pre > code is problematic in regards to introducing extra whitespace for text selection, I think we should introduce a new exclusive HTML class for syntax highlighting and use that everywhere.

How that will work in markdown code sections?

[silverwind]

Good point, if the markdown renderer can only output pre > code, we have to cover it via .markdown pre > code. On the other hand, I think some more expermentation is neccessary if pre > code can be made to work in regard to copy/paste.
