yes, but one of them would be sufficient.

OTOH we have not a handy code for branching.

Do you know case, "p" receiving M- numeric arg must fail, so C-u NUMBER 
through "P" is needed?

Don't suggest additional code but a better use of "P" - no parallel 
implementations. Having "P" as a branch-flag not affected by "p"
