Currently perforce will perform a sync on 2 occasions,
1. If the source directory is empty. or
2. If the vcs revision is null

This means that every time you create a plan on the same depot view it will do a full checkout (even though the source is there). This can be painful for large depots.

We may need to check this behaviour is logical (maybe it should only use -f for case 1. and not 2.) or add the option to turn off the -f all together.
