But "update" should mean "replace git add -u with git add -u .", which
is the portable way to do the same.

The introduction of the config variable is a non-event if you already
use the portable . notation.

I think is still makes sense to have a config variable, so that people
who want the new behavior can get it ASAP. Right after 1.8 is out, I'll
still have machines where I'm too lazy to install a brand new Git, and
I'll want to get the 1.8 goodness for free ;-).
