Whitespace handling is done per-styler. The sample styler used for JS assigns token_tab and token_space classes to regions of text, then uses CSS to set the background for them.

TextMateStyler should support this. It should be done in a grammar-independent way so you don't have to build whitespace-detection into your grammar.

This might also be worth pulling up into an API for all stylers, so that we can support a user pref to always show whitespaces in any file type. (This is one of my current pet peeves -- every time I check out the editor code I need to hack styler.js and set whitespacesVisible = true).
