This *almost* works, but my language-grammar-fu is not strong enough. In 
the C grammar, for example, I haven't been able to come up with a scoping 
rule to select '^\s*' that doesn't interfere with existing rules which 
contain whitespace anchored at the start of the line (like pre-processor 
directives).  I think I'd have to edit every existing rule which contains 
'^\s*' to capture that leading whitespace into its own scope.  That's way 
more grief than I'm looking for.

And, as I reflect on it some more, just re-assigning the tab key isn't 
exactly what I want.  I also want cmd-] to insert hard tabs to indent a 
block, which wouldn't happen with this technique. Though I suppose I 
could write another command for cmd-] that would do that.
