If it was up to me I'd ban \t character altogether from source code and just use plain spaces - but a lot of sources, especially in C, are indented like this:
- no indent
- 4 spaces
- \t + 4 spaces
TextMate has trouble with it - it has a single setting for indentation (normally 2 or 4 depending on language, 8 is rare), and meaning of \t (universally 8 if present at all).
Am I missing some setting to get it work properly?
