Documentation

If non-nil, registers are supported via numeric prefix arg.

If the value is t, any numeric prefix arg in the range 0 to 9 will be interpreted as a register number. If the value is not-ctrl-u, using C-u (universal-argument) to enter a numeric prefix is not interpreted as a register number. If the value is ctrl-u-only, only numeric prefix entered with C-u (universal-argument) is interpreted as a register number.
