this isn't really feasible. You can't unbundle on top of a missing node.

use this code, which doesn't delete tags ;)

using the -r option to convert in fixed increments might also
help. Or we can try to convert tags to commit-like objects, so that we
can use the actual time when a tag is removed for systems that provide
that information, like SVN.
