bug#9970: 24.0.90; Commandify set-frame-{height,width}

[Harald Hanche-Olsen]

This is a feature request, not a bug report:

I suggest turning set-frame-width and set-frame-height into commands,
so that you can type, e.g., C-u 80 M-x set-frame-width RET in order to
set the width of the current frame to 80 characters. Without a prefix
character, the commands should prompt the user. (I see no reason to
allow the specification of a frame other than the current, or to
support the PRETEND arg, in interactive use.)
