Correct. And BTW, the "numerical argument" is nothing more than
`prefix-numeric-value' applied to the raw prefix arg value (the "prefix value
introduced with C-u").
> So if I do M-NUMBER, "P" should send nothing.
No. There is _always_ a raw prefix-argument value, even if you use none of
`M-NUMBER', `C-NUMBER', `M--', or `C-u'. If you use none of those then the raw
prefix argument value is nil.
If you use `M-NUMBER' or `C-NUMBER' or `C-u NUMBER' then the raw value is
NUMBER. This is mentioned in the doc we pointed you to:
"M-3 M-x display-prefix -| 3 ; (Same as `C-u 3'.)"
"M-- 7 M-x display-prefix -| -7 ; (Same as `C-u -7'.)"

I don't understand you. Why `M-command'?
But yes, `C-u' by itself gives 1 for "p" and (4) for "P".
