Eliminate most core code byte-compile warnings. 2009-12-18 Aidan Kehoe <kehoea@parhasard.net> * alist.el (modify-alist): * autoload.el (update-autoload-files, autoload-print-form): * bytecomp.el (batch-byte-compile-1) (byte-compile-multiple-value-call, byte-compile-funcall) (byte-compile-insert, byte-compile-concat, byte-compile-list) (byte-compile-normal-call, byte-compile-flush-pending): * cl-macs.el (letf): * cl.el: * disass.el (disassemble-1): * easy-mmode.el (easy-mmode-define-syntax): * faces.el (set-face-parent): * files.el (cd): * finder.el (finder-list-matches, finder-list-keywords) (finder-compile-keywords): * frame.el (frame-notice-user-settings) (frame-remove-geometry-props): * ldap.el (ldap-delete-entries, ldap-modify-entries) (ldap-add-entries): * loadhist.el (unload-feature): * map-ynp.el (map-y-or-n-p): * menubar-items.el (default-menubar): * mouse.el (default-mouse-track-next-move-rect) (default-mouse-track-next-move-rect) (default-mouse-track-cleanup-hook) (default-mouse-track-cleanup-extent): * mule/ethio-util.el (ethio-fidel-to-sera-buffer) (ethio-modify-vowel): * obsolete.el: * package-get.el (package-get-update-all): * package-ui.el (pui-list-packages) (pui-install-selected-packages, pui-install-selected-packages): * select.el (select-make-extent-for-selection) (dehilight-selection): * simple.el (clone-buffer): * term/tvi970.el: * term/wyse50.el: * unicode.el: (load-unicode-tables): * x-font-menu.el (fc-make-font-menu-entry) (x-reset-device-font-menus-xft): * x-misc.el (x-init-specifier-from-resources): Eliminate byte-compile warnings, with the exception of Stephen's various non-defined fontconfig functions, as I don't know if he plans to add them and is keeping the warnings around as a reminder. The warnings actually eliminated involve i) using mapcar instead of mapc where the result is discarded and ii) using a lambda quoted as data in a context where it is unequivocally used as a function.
