This discussion started in part because of the perceived difficulty of
getting a patch integrated to implement "bzr unshelve --keep"
(https://bugs.launchpad.net/bzr/+bug/492091)
bzr shelves are not very usable without this option, you can't go back
and forth between shelved versions.
The patch would change bzrlib/shelf_ui.py:Unshelver.from_args to set 
delete_shelf to False when "--keep" is passed.  So about 3 lines total.

Would such a patch need copyright assignment?
Even if it does, given the above description, a bzr developer can
reproduce the change needed in a few seconds... 
Can you please help get this solved?
