Re: [RFC/PATCH] add: warn when -u or -A is used without filepattern

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
  option)

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

What about 'grep' and 'clean'? I think at least 'clean' should go
tree-wide default too. I don't mind grep go the same way either but I
think people voiced preference in current behavior..
