And then the number could mean the verbosity level, e.g. `C-1 C-x C-e'
prints octal and hex, and `C-2 C-x C-e' prints octal, hex and a character.

But I don't see how to insert different representations to the current
buffer instead of displaying them in the echo area since `C-u C-1 C-x C-e'
and `C-1 C-x C-e' have the same numeric argument `1'.
