[p4] Erasing sync history?

[Stephen Vance]

p4 flush #none

(may need to be escaped or quoted depending on your shell) tells 
Perforce that you have no versions but that it doesn't need to worry 
about the disk.

p4 sync #none

Does the same thing but lets Perforce manage the disk space. This is 
safer and what your developer should do in the future because it won't 
delete files that are open for edit or add.

Turning in the "rmdir" option in the client spec will tell Perforce to 
remove any directory that it removes the last element from. That way 
when you sync to none, if there are any directories left, you know that 
you had some uncontrolled files or some files open for edit.

You can force the "rmdir" option to be on by default with a form out 
trigger on the client form.
