Ah, so it is. Then I'm disturbed that browsers render a tab as 8 spaces.

https://developer.mozilla.org/en/CSS/tab-size was just implemented in the newest browsers, for all your tab-sizing needs :)

8 is the traditional size of tabs though, isn't it? Seems like a reasonable default. That's partially why some teams (mine included) discourages the use of tabs in source code - its appearance varies depending on what's rendering it, affecting code readability.

Patches accepted!
