Hi Jeff,
thanks for your quick reply.

Since then I looked at the man page (I should have done that right
away ;), and it says under the description of -u that "If no paths are
specified, all tracked files in the current directory and its
subdirectories are updated." So this is indeed the intended
behaviour, but I was just not aware of it. Oh well, sorry for the
noise.

I don't really know which would I prefer.
I was updating some Javadoc documentation in Eclipse, and checking the
generated docs in terminal, deep down in an untracked subdir, and
performed some 'add -u ; commit --amend' from there (and was rather
surprised after the fifth amend to see all the changes still in the
worktree). Doing perform the desired add -u from there I should have
run 'git add -u ../../../../../..', what doesn't seem very convenient.
But since this was the first time I've done that since 2007-08-16, I
guess it's not a very common use case.
