If "git add -u ../.." (I mean "the grand parent directory", not "an
unnamed subdirectory") did not work 

In git.git:

$ cd t
$ git grep addremove -- ../
fatal: git grep: cannot generate relative filenames containing '..'

So here's a fix for that. And a configurable solution for add and grep's
scope as a follow-up. I did not look at any other commands yet.

Thanks.  This was oa breakage I pointed out in an earlier message in this
discussion, and it is worth fixing.

Your patch is queued in 'pu', but it seems to break the exit status in a
strange way with my limited test.

Here is a non-broken behaviour without the "look in uplevel":

: git.git/cb/maint-1.6.3-grep-relative-up; ./git grep adddelete .
: git.git/cb/maint-1.6.3-grep-relative-up; ./git grep adddelete .; echo $?
1
: git.git/cb/maint-1.6.3-grep-relative-up; ./git grep adddelete . >/dev/null; echo $?
1

Now we go down, and grep from an uplevel:

: git.git/cb/maint-1.6.3-grep-relative-up; cd t
: t/cb/maint-1.6.3-grep-relative-up; ../git grep adddelete ..
: t/cb/maint-1.6.3-grep-relative-up; ../git grep adddelete .. ; echo $?
1
: t/cb/maint-1.6.3-grep-relative-up; ../git grep adddelete .. >/dev/null; echo $?
0

The command should not give different exit status depending on the
destination of standard output stream.
