Do not break lines within :option: references

Thank you for reporting this @marxin.

The problem with white-space: nowrap is that it will break the layout for long .literals.

Maybe we can assume that users will choose to use a block literals for these cases, or we could make the .literal inline-block elements instead. This options requires more testing to make sure nothing breaks and some tweaking to paddings and positionings to make sure the inline-block elements don't shift the line height.

What do you think @agjohnson?

I did some initial testing and the code bellow works without any line shifting. We'd just need to test it for possible edge cases.
