When verifying setting a Z register via ptrace we check each byte by hand, iterating over the buffer using a pointer called p and treating each register value written as a test. This creates output referring to "p[X]" which is confusing since SVE also has predicate registers Pn. Tweak the output to avoid confusion here.
