Users can do --depth=2147483648 for infinite depth now. It just looks
ugly. So make "0" special (i.e. infinite depth) at plumbing/protocol
level.
To make it even more user friendly, "git fetch" accepts --depth=inf as
an alternative to --depth=0. "git clone" also can. It just does not
make much sense for doing "git clone --depth=inf"
