changeset 976:bed842762447

amend: add -D/--current-date option, just like mq's qrefresh has

Carefully designed so we can easily add -D to other changeset-creating
commands (probably anything that takes -d), and so that we can add
-U/--current-user as well. When that's done, the date and user options
should be very similar to those in MQ.
