(On my mobile at the moment so lacking in linr breaks.)
Sorry, I obviously didn't explain the change properly. The new behaviour is both expected and necessary to have the clean separation between levels of nesting: if a (P) occurs inside multiple braces, the immediately surrounding level deals with the parameter name, and the outer level deals with the value. That's the only way to implement this in a workable fashion. If the old kludge where it's mixed together is needed for compatibility, we'll need to go back to the old state (and leave it permanently - it is not compatible with a properly nested form of the (P) flag). Or, of course, we can update the documentation, or, yuk, use a different flag and deprecate the old one.
