There are sane people who think you shouldn't be importing version
control history into an existing non-empty repository. It basically
means rewriting history; the question "what did I have in this
repository last Tuesday" changes.

The specification of {date} makes no sense if revisions are not linearly
date-ordered. This is not an implementation issue.

(When this has come up in the past, brane has said that in an
Apache-style repository, {date} *probably* has a well-defined meaning
for a particular path, even if it doesn't for the repository root. But
that's hand-wavy, and our command-line and API specification does not
resolve {date} with reference to a particular path.)
