[pca] Changes in Recommended OS Cluster

[Martin Paul]

A PCA user pointed me at the README of the current "Recommended OS Patchset". 
Besides a cosmetic change (the term "Patch Cluster" has been replaced by 
"Patchset") there is this note:

   The patch inclusion criteria have been extended to include patches for
   selected issues identified by Oracle Proactive Services and the Oracle
   Technical Support Center.

When comparing yesterday's and today's patchdiag.xref, I had already noticed 
that there are hundreds of patches which are suddenly marked as "R" 
(Recommended). I guess the above note explains this. So don't be surprised when 
"pca -l missingr" suddenly shows a lot more patches than yesterday.

Martin.
