(gomoku-mode): Doc fix. Add call to kill-all-local-variables,
for global-font-lock-mode.
(gomoku): Do not call gomoku-switch-to-window directly, else the
player is asked the startup questions twice after a killed game.
(gomoku-prompt-for-other-game): Throw an error if no new game,
since otherwise answering no after a killed game has no effect.
(gomoku-switch-to-window): Use gomoku-buffer-name.
(gomoku-mouse-play): Use it to play nearest to mouse click.
(gomoku-terminate-game): Factorize messages.
(gomoku): Allow interactive passing of board size. Don't make a fuss
about restarting a game that hasn't progressed.
(gomoku-offer-a-draw): Give user the choice it pretended to give.
(gomoku-point-x): Deleted function.
(gomoku-point-y, gomoku-point-square): Simplified because point is
always on a square.
(gomoku-goto-xy, gomoku-plot-square): Fix line count due to
intangible newlines.
(gomoku-init-display): Once again fairly fast due to minimization of
characters in buffer and text-property operations. Cursor cannot be
be off a square.
(gomoku-display-statistics): Simplified equivalently.
(gomoku-winning-qtuple-beg, gomoku-winning-qtuple-end)
(gomoku-winning-qtuple-dx, gomoku-winning-qtuple-dy): Pseudo variables
only used for non-functional argument passing deleted.
(gomoku-cross-winning-qtuple): Accordingly deleted function and
(gomoku-check-filled-qtuple): Accordingly adapted.
(gomoku-cross-qtuple): Don't be confused by tabs.
(gomoku-move-down, gomoku-move-up): Simplified because point is always
on square.
(gomoku-beginning-of-line, gomoku-end-of-line): New commands necessary
because intangible newlines perverted these.
(gomoku-mode-map): Added numeric keypad for 8 directions, changed
comments to lowercase (C-c rather than C-C), added SPC to play and
undo's binding to go back.
(gomoku-emacs-won, gomoku-font-lock-O-face, gomoku-font-lock-X-face)
(gomoku-font-lock-keywords): New variables.
(gomoku-mode): Use it and make buffer read-only for user.
(gomoku-terminate-game): Remove (ding) -- maybe should be optonal.
(gomoku-init-display): Rewritten, makes fields intangible so you
can't go in between. Make free fields have mouse-face.
(gomoku-cross-qtuple): Take account of intangible text, and that
empty lines are now really empty.
(gomoku-move-left, gomoku-move-right): Removed thanks to intangibility.
(gomoku-move-ne, -se, -nw, -sw): Use normal left / right motion.
for wins and losses.
(gomoku-number-of-emacs-wins): Renamed from gomoku-number-of-wins.
(gomoku-number-of-human-wins): Renamed from gomoku-number-losses.
