Can't copy paths between different components.

[tpn]

In a multi-component repo, the current hooks prevent copying of files between components, e.g. you can't do this in a commit:

A /bar/trunk/widget.java (from: /foo/trunk/widget.jar:801)

Some users have reported that they would like to be able to do this, as it's a part of normal refactoring, and it keeps the version history in tact. (The current work-around is to manually copy the file.)

Action: review current behavior, determine if default is still the most applicable, and either add an override facility, or change the default behavior to allow such copies.
