Remove some redundant functions, change others to labels, lisp/
lisp/ChangeLog addition:
2012-05-05 Aidan Kehoe <kehoea@parhasard.net>
Remove some redundant functions; turn other utility functions into
labels, avoiding visibility in the global namespace, and reducing
the size of the dumped binary.
* auto-save.el (auto-save-unhex): Removed.
* auto-save.el (auto-save-unescape-name): Use #'string-to-number
instead of #'auto-save-unhex.
* files.el (save-some-buffers):
* files.el (save-some-buffers-1): Changed to a label.
* files.el (not-modified):
* gui.el (make-gui-button):
* gui.el (gui-button-action): Changed to a label.
* gui.el (insert-gui-button):
* indent.el (indent-for-tab-command):
* indent.el (insert-tab): Changed to a label.
* indent.el (indent-rigidly):
* isearch-mode.el:
* isearch-mode.el (isearch-ring-adjust):

a label.
* isearch-mode.el (isearch-highlight):
* isearch-mode.el (isearch-make-extent): Changed to a label.

* itimer.el (itimer-decrement): Removed, replaced uses with decf.
* itimer.el (itimer-increment): Removed, replaced uses with incf.
* itimer.el (itimer-signum): Removed, replaced uses with minusp, plusp.
* itimer.el (itimer-name):
* itimer.el (check-itimer): Removed, replaced with #'check-type calls.
* itimer.el (itimer-value):
* itimer.el (check-itimer-coerce-string): Removed.
* itimer.el (itimer-restart):
* itimer.el (itimer-function):
* itimer.el (check-nonnegative-number): Removed.
* itimer.el (itimer-uses-arguments):
* itimer.el (check-string): Removed.
* itimer.el (itimer-function-arguments):
* itimer.el (itimer-recorded-run-time):
* itimer.el (set-itimer-name):
* itimer.el (set-itimer-value):
* itimer.el (set-itimer-value-internal):
* itimer.el (set-itimer-restart):
* itimer.el (set-itimer-function):
* itimer.el (set-itimer-is-idle):
* itimer.el (set-itimer-recorded-run-time):
* itimer.el (get-itimer):
* itimer.el (delete-itimer):
* itimer.el (start-itimer):
* itimer.el (activate-itimer):
* itimer.el (itimer-edit-set-field):
* itimer.el (itimer-edit-next-field):
* itimer.el (itimer-edit-previous-field):
Use incf, decf, plusp, minusp and the more general argument type
checking macros.
* lib-complete.el:
* lib-complete.el (lib-complete:better-root): Changed to a label.
* lib-complete.el (lib-complete:get-completion-table): Changed to
a label.
* lib-complete.el (read-library-internal): Include labels.
* lib-complete.el (lib-complete:cache-completions): Changed to a
label.
* minibuf.el (read-buffer): Use #'set-difference, don't reinvent it.
* newcomment.el (comment-padright): Use a label instead of
repeating a lambda expression.
* packages.el (package-get-key):
* packages.el (package-get-key-1): Removed, use #'getf instead.
* simple.el (kill-backward-chars): Removed; this isn't used.
* simple.el (what-cursor-position):
(lambda (arg) (format "%S" arg) -> #'prin1-to-string.
* simple.el (debug-print-1): Renamed to #'debug-print.
* simple.el (debug-print): Removed, #'debug-print-1 was equivalent.
* subr.el (integer-to-bit-vector): check-nonnegative-number no
longer available.
* widget.el (define-widget):
* widget.el (define-widget-keywords): Removed, this was long obsolete.
