This operation is seriously broken. The Z number should be incremented, the tag should continue pointing at the (now known to be) broken version. That's exactly what the patchlevel number is for.

If users want to know if there are important security updates around, they will look at the version number. If you change the revision which the tag points to you will _seriously_ confuse users, a lot more than a long list of patchlevel versions will ever do.
