Before, the code was not consistent. These values cannot exceed 2**31 - 1 so there's no need to make them unsigned. (x_x_to_emacs_modifiers): Accept int and return EMACS_INT. (x_emacs_to_x_modifiers): Accept EMACS_INT and return int. (x_x_to_emacs_modifiers, x_emacs_to_x_modifiers): Reject non-integers as modifiers. * xterm.h (x_x_to_emacs_modifiers): Adjust to signature change.
