This is mostly useful if the number of projects to switch is many (e.g. all of Android) and a large number of them are behind the current manifest revision. We wind up needing to run git just to make the working tree match, and that often makes the command take a couple of seconds longer than we'd like. Signed-off-by: Shawn O. Pearce <sop@google.com>
