CodeRay converts tabs into spaces; I would prefer it not do that. I would like to keep things in alignment and have more accurate copy-pasting. I can handle the size of the tabs with the tab-size CSS property.

I've patched it like so greasyfork-org/greasyfork@e483752 but I think it would be good to have this as a built-in option. Maybe handle it by passing -1 to tab_width?

I've read #61, which contains this delicious quote:

I don't want to have this discussion. If anybody insists on using tabs, please fork CodeRay.

Not sure if this represents a general bias against tabs in general or just that specific suggestion...
