The above is not specific enough to judge if you found a bug or if it is a
user error.

IIRC, --depth=<n> is not "deepen by <n>", but "make sure I have at least
<n> from the updated tip(s)".  The shallow-clone hack gives you quite
useless (even though it may be internally consistent) semantics if you
shallow-cloned way in the past and fetched with --depth after the other
side added many more commits than <n>, as you cannot guess what the right
value of <n> should be without actually fetching without --depth.
