[RFC/PATCH 1/8] update-index: add untracked cache notifications

[Christian Couder <christian.couder@gmail.com>]

Doing:

  cd /tmp
  git --git-dir=/git/somewhere/else/.git update-index --untracked-cache

doesn't work how one would expect. It hardcodes "/tmp" as the directory
that "works" into the index, so if you use the working tree, you'll
never use the untracked cache.

With this patch "git update-index --untracked-cache" tells the user in
which directory tests are performed and in which working directory the
untracked cache is allowed.
