A common workflow in large projects is to chdir into a subdirectory of
interest and only do work there:
cd src
vi foo.c
make test
git add -u
git commit
The upcoming change to 'git add -u' behavior would not affect such a
workflow: when the only changes present are in the current directory,
'git add -u' will add all changes, and whether that happens via an
implicit "." or implicit ":/" parameter is an unimportant
implementation detail.
The warning about use of 'git add -u' with no pathspec is annoying
because it serves no purpose in this case. So suppress the warning
unless there are changes outside the cwd that are not being added.
