builtin/replace: teach listing using short, medium or full formats
By default when listing replace refs, only the sha1 of the replaced objects are shown. In many cases, it is much nicer to be able to list all the sha1 of the replaced objects along with the sha1 of the replacment objects. And in other cases it might be interesting to also show the types of the replaced and replacement objects. This patch introduce a new --format=<fmt> option where <fmt> can be any of the following: 'short': this is the same as when no --format option is used, that is only the sha1 of the replaced objects are shown 'medium': this also lists the sha1 of the replacement objects 'full': this shows the sha1 and the type of both the replaced and the replacement objects Some documentation and some tests will follow.
