Yes, that is exactly why I asked you to suggest improvements to that

If that is really the case and you want the full-tree behaviour, you
would have been using "git add -u :/" already, and then you wouldn't
have seen the warning.

Why do we have this thread then?

The reason may well be "I've heard about the :/ magic pathspec, and
I thought I understood what it does at the intellectual level, but
it has not sunk in enough for me to use it regularly".

The warning, and "you can squelch with either :/ or ." to train the
fingers (not "set once and forget"), is exactly to solve that
problem now *and* *in* *the* *future* during the 2.0 transition

You also said that it often is the case for you that you stay in a
narrow subtree without touching other parts of the tree. If that is
the case, you may *not* want 2.0 behaviour, which forces Git to run
around the whole tree, trying to find modified paths outside of your
corner that do not exist, wasting cycles.  You want "git add .", and
you are better off starting to train your fingers so that they type
that without thinking now.  I think the conclusion during the old
discussion was not "we want configuration", but "this is not per
user and configuration is a poor approach. Depending on what you are
working on right now, you would want 'only here' sometimes and
'whole tree' some other times".

Not at all. Even you who visit this list often do not regularly use
the ":/" to affect the whole tree and see the warning. What do you
imagine other people, who do not even know about this list do and
say, at sites like stackoverflow where uninformeds guide other

  Q. Help, Git 1.8.2 is giving me this warning. What to do?
  A. Set this configuration variable. No other explanation.

Renaming use2dot0 to future does not solve anything.

That is not an argument for adding temporary configuration, as it is
not the only or even the best way to do so.  It can be easily an
cleanly achieved by cooking in next until 2.0.

An ulterior motive for going that way is to encourage more people to
run 'next' ;-). Recently we are seeing bugs discovered only after topics
graduate to 'master', which is not a good sign X-<.
