I don't think that you can specify the tab-width. I *think* it always  
is counted as 4 spaces in the code,
but I might be mistaken. It should be found in the code somewhere,  
though.
If this is bothering you badly, you could try to "preprocess" the  
grammars, but I'd advise against it.
Or instruct your editor to always use spaces instead of tabs.

This discussion of course is a popular means of igniting a long flame  
war ;)

But thanks for reminding me of this, I haven't thought of that  
pitfall yet, as I'm going to redo message output for
v3 soon. Maybe I can figure out a way around (probably not...).
