Ah, probably that was it. It works fine now with your latest commit.

Yeah, when I thought about it I figured that it would be too messy to  
have it work real-time, and it is fine as it is, but maybe a little  
comment on the page would be helpful (to the effect: "Note: This will  
only take effect if you...), exactly because the behavior is not  
Well, the only thing I found irritating is the lack of a shortcut for  
the Languages editor and for the Preferences editor, or did I miss  
them? Having to close the bundle editor for effects to show is fine  
(though a save button as Tim says is even better), but having to  
press three buttons to get back where you were is not.

ah, the dangers of using the small unpleasant window to edit, rather  
than a wonderful textmate window :-)

Oh, we can just remove that, I was using it to try to use that as  
space, as the Python bundle does, or at least that's what I thought  
they do.

Is that what is being used in the Python code? \x{nnnn} support would  
be great, as well as explanation of one or two of the choices for  
nnnn. For instance, I still have no idea what em-space is, guessing  
some unicode character.

But really, why doesn't plain old space work, both here and in ctags?  
It seems to be completely ignored if it's at the beginning.
Btw, can you make it so that it looks at the number of "sub" in front  
of section, and puts an equal amount of em-spaces? That would be divine.
