-p should include ugp by default. Pretty much EVERY standard UNIX command uses -p == permissions (tar, pax, cp, scp, ... ). This is going to be expected behavior. Anything less is going to be extremely confusing and cause endless issues.

+1 This is a change from current behaviour, but I'd argue it's a bugfix rather than an incompatibility and I'd be very surprised if it creates any problems. messed up the issues
Not going to make 0.16.2. Moving this 0.17. Could backport to 0.16.3 if there is one.
3099_20080402b.patch:
-p[rbugp] Preserve status
r: replication number
b: block size
u: user
g: group
p: permission
-p alone is equivalent to -prbugp
