That's apparently because tags are not considered when truncating the
commit list. The patch below fixes it, and fetches the right number of
commits for each tag. However the correct fix is probably to not fetch
historical tags at all.

There's also a problem with the packing, a clone --depth 1 currently
results in a pack that's about 3 times as large as it should be.
