 - add: make "add -u" update full tree without pathspec

A three-phase migration that:

 (1) first only warns when we would deviate from traditional behaviour and
     suggest adding "." if the user wants to limit it to cwd, but doesn't
     actually add full-tree, in the next release;

 (2) warn that we have changed the behaviour and suggest adding "." if the
     user wants to limit it to cwd, and actually do full-tree, in 1.8.0;

 (3) remove the warning, in 1.8.X (for X at least 2 or more).

would be a good way forward.

... and here is how the first step would look like.

... and here is the second step meant for 1.8.0 release.

The third step for 1.8.2 or later should be trivially obvious, so I
wouldn't bother sending it out.

Subject: [PATCH] add -u: tree-wide without pathspec

The warning still remains in this version, but has to stay here
to help people who skipped late 1.7.X releases.  Unfortunately
we do not have a good way to let people who have already heard
about the transition to squelch it yet. That has to wait until
we have a magic ":/" pathspec that would mean to match from the
top of the working tree no matter where $cwd is.  At that point,
people can say "git add -u :/" to squelch the warning.
