* lisp/simple.el (prefix-command-echo-keystrokes-functions) (prefix-command-preserve-state-hook): New hooks. (internal-echo-keystrokes-prefix): New function. (prefix-command--needs-update, prefix-command--last-echo): New vars. (prefix-command-update, prefix-command-preserve): New functions. (reset-this-command-lengths): New compatibility definition. (universal-argument--mode): Call prefix-command-update. (universal-argument, universal-argument-more, negative-argument) (digit-argument): Call prefix-command-preserve-state. * src/keyboard.c: Call internal-echo-keystrokes-prefix to build the "prefix argument" to echo. (this_command_key_count_reset, before_command_key_count) (before_command_echo_length): Delete variables. (echo_add_key): Always add a space. (echo_char): Remove. (echo_dash): Don't give up when this_command_key_count is 0, since that is now the case after a prefix command. (echo_update): New function, extracted from echo_now. (echo_now): Use it. (add_command_key, read_char, record_menu_key): Remove old disabled code. (command_loop_1): Don't refrain from pushing an undo boundary when prefix-arg is set. Remove other prefix-arg special case, now handled directly in the prefix commands instead. But call echo_now if there's a prefix state to echo. (read_char, record_menu_key): Use echo_update instead of echo_char. (read_key_sequence): Use echo_now rather than echo_dash/echo_char. (Freset_this_command_lengths): Delete function. (syms_of_keyboard): Define Qinternal_echo_keystrokes_prefix. (syms_of_keyboard): Don't defsubr Sreset_this_command_lengths. * lisp/simple.el: Use those new hooks for C-u. (universal-argument--description): New function. (prefix-command-echo-keystrokes-functions): Use it. (universal-argument--preserve): New function. (prefix-command-preserve-state-hook): Use it. (command-execute): Call prefix-command-update if needed. * lisp/kmacro.el (kmacro-step-edit-prefix-commands) (kmacro-step-edit-prefix-index): Delete variables. (kmacro-step-edit-query, kmacro-step-edit-insert): Remove ad-hoc support for prefix arg commands. (kmacro-step-edit-macro): Don't bind kmacro-step-edit-prefix-index. * lisp/emulation/cua-base.el (cua--prefix-override-replay) (cua--shift-control-prefix): Use prefix-command-preserve-state. Remove now unused arg `arg'. (cua--prefix-override-handler, cua--prefix-repeat-handler) (cua--shift-control-c-prefix, cua--shift-control-x-prefix): Update accordingly. (cua--prefix-override-timeout): Don't call reset-this-command-lengths any more. (cua--keep-active, cua-exchange-point-and-mark): Don't set mark-active if the mark is not set. |
