Is it hard to write a command that simply goes through all the files  
in the current project and toggles between the two tabbing styles?  
Unless I'm mistaken, Allan might have already written one such.

Then all you'll have to do is run this command before you commit your  
changes. You could perhaps even put this command in a .textmate_init  
file so that you don't have to remember running it each time, though  
I guess this might be a bit more complicated.

Sure it is a bit more work than if the editor supported it natively,  
but it's doable I think.
