Currently, if a poster wants to format an error (e.g. from a console), she has to format it either as a blockquote, or a code block.

Both options are inadequate for formatting console output, as such output is neither a quote, nor a code block.

One issue with using code block formatting, is the poster will have to de-highlight that block (`language: lang-none`) as to not unintentionally color any phrases.  

Further more, code blocks don't wrap their text (due the underlying `<pre>` tags), so in order for the output to be readable the poster would have to break the output lines, in most cases.

Let's have a predefined formatting option for console output, with the said features, i.e. pre-formatted with word-wrapping, no highlight (or perhaps proper highlight for different outputs like Apache logs etc.), and with its own style to differ it from other formatted blocks.
