Most git commands that can be used with our without a filepattern are
tree-wide by default, the filepattern being used to restrict their scope.
A few exceptions are: 'git grep', 'git clean', 'git add -u' and 'git add -A'.

The inconsistancy of 'git add -u' and 'git add -A' are particularly
problematic since other 'git add' subcommands (namely 'git add -p' and
'git add -e') are tree-wide by default.

Flipping the default now is unacceptable, so this patch starts training
users to type explicitely 'git add -u|-A :/' or 'git add -u|-A .', to prepare
for the next steps:

* forbid 'git add -u|-A' without filepattern (like 'git add' without

* much later, maybe, re-allow 'git add -u|-A' without filepattern, with a
  tree-wide scope.

A nice side effect of this patch is that it makes the :/ special
filepattern easier to discover for users.

When the command is called from the root of the tree, there is no
ambiguity and no need to change the behavior, hence no need to warn.

Changes since v1:

* Do not warn from the root of the tree.

* Say explicitely "Git 2.0" to announce the change.

(plus fix a C99 style issue)
