Is there some reason that this cannot be pushed into the repository
itself (i.e., used like a blur/clean thing)?  See the bottom of this
page: http://progit.org/book/ch7-2.html

I.e., we just automagically detabify when staging.

It seems inappropriate to expect everyone to fuss with his/her own
repository to get this behavior.  Shouldn't we do it once on the shared
repo and we all get it for free?
