[PATCH 3/3] git add <pathspec>... defaults to "-A"

[Junio C Hamano <gitster@pobox.com>]

Make "git add <pathspec>..." notice paths that have been removed
from the working tree, i.e. a synonym to "git add -A <pathspec>...".

Given that "git add <pathspec>" is to update the index with the
state of the named part of the working tree as a whole, it makes it
more intuitive, and also makes it possible to simplify the advice we
give while marking the paths the user finished resolving conflicts
with.  We used to say "to record removal as a resolution, remove the
path from the working tree and say 'git rm'; for all other cases,
edit the path in the working tree and say 'git add'", but we can now
say "update the path in the working tree and say 'git add'" instead.
