I'd hesitate to ever run it over the entire codebase.

* It will ruin plain git blame, since so much will point to that particular
   commit. Yes, you can use `git blame -w` to avoid whitespace changes, 
but that
   does not catch rewrapped lines.

* Open changes would need to be rebased on top of it. When would be a 
good point
   in time with few open changes?

* Which branch do you run it in? If an early one, there's many merges to 
do. If
   a late one, all the subsequent merges are tricky.

It is quite a bit of pain while the benefit isn't that big. Actively 
worked on
areas would shape up incrementally anyway and the other areas are not 
read that
much, so the damage of inconsistent formatting is limited.

For the above reasons I'd lean towards not running it globally and just 
using it
on new changes.
