Summary: If you are not having problems with the files, mentally replace the P 
with a U and be happy, i.e., ignore the implementation detail that should 
never have been shown to anyone but the CVS developers.


Long version:
U = updated file
P = updated file by transferring only a patch.

 From the user's perspective U = P.
 From the network's perspective P smaller than U.

A discussion of the issue:

Due to the number of times I have been asked about it at work, I tend to agree 
with Greg, it would be a good Idea to in a future version of CVS to either:
1) change the P to a U in the source.
2) make a command line option to show P if the user WANTS to know when patches 
are being used, but make the default just show U.
