[TxMt] Indent size different from tab size

Hello,

I am working a lot with source code written using Emacs on Linux. The prevailing convention is that tabs are presented as 8 spaces, but indents are only 4 spaces. Indenting will insert spaces, and Emacs seems to swap groups of 8 spaces for a tab.

If I use a tab size of 8 in Textmate, the source files display correctly. Sadly, there is no way to tell Textmate to use an indent size of 4.

It would be very useful is it was possible to tell TextMate to: 1. Draw tabs as 8 spaces 2. Use spaces when indenting 3. Intend with 4 spaces, not the 8 spaces from a tab

Is there any way to do this with TextMate at the moment?

I'm using TextMate 1.5.3 (1215)
