I'd rather we reserve 0 for unlimited fetch, something we haven't done
so far [1]. And because "unlimited clone" with --depth does not make
sense, --depth=0 should be rejected by git-clone.

[1] If we don't want to break the protocol, we could make depth
0xffffffff a special value as "unlimited" for newer git. Older git
works most of the time, until some project exceeds 4G commit depth
history.
