[xemacs-hg @ 2002-03-15 07:43:14 by ben] .cvsignore: ignore .tmp files that are getting auto-created by VC. Makefile.in.in: Use -no-packages to avoid problems with package files shadowing core files (e.g. unicode.el in mule-ucs). alloc.c, emacs.c, lisp.h: add new -no-packages. make sure list of args for sorting is actually correct. clean up arg parsing code. xemacs.mak: Use -no-packages to avoid problems with package files shadowing core files (e.g. unicode.el in mule-ucs). Makefile: Use -no-packages to avoid problems with package files shadowing core files (e.g. unicode.el in mule-ucs). mule\chinese.el, mule\japan-util.el: fix warnings. behavior-defs.el: fix errors with require. bytecomp-runtime.el: add new funs {when,and}-{f}boundp, clean up docs. cus-edit.el: pretty-print values. dump-paths.el, find-paths.el, startup.el, setup-paths.el: fix problems/inconsistencies parsing options. support new -no-packages option. merge code duplication in dump-paths and startup. lisp-mode.el: indent macrolet and labels correctly. update comments about lisp-indent-function. flet already handled in cl. apropos.el, auto-save.el, buff-menu.el, cl-extra.el, dragdrop.el, faces.el, files.el, fill.el, font-lock.el, font.el, gtk-faces.el, gui.el, help.el, hyper-apropos.el, info.el, isearch-mode.el, keymap.el, lisp-mnt.el, mouse.el, package-admin.el, package-get.el, printer.el, process.el, resize-minibuffer.el, simple.el, toolbar-items.el, wid-edit.el, win32-native.el: fix warnings. very-early-lisp.el: update docs. mule\chinese.el, mule\japan-util.el: fix warnings. mule\chinese.el, mule\japan-util.el: fix warnings. behavior-defs.el: fix errors with require. bytecomp-runtime.el: add new funs {when,and}-{f}boundp, clean up docs. cus-edit.el: pretty-print values. dump-paths.el, find-paths.el, startup.el, setup-paths.el: fix problems/inconsistencies parsing options. support new -no-packages option. merge code duplication in dump-paths and startup. lisp-mode.el: indent macrolet and labels correctly. update comments about lisp-indent-function. flet already handled in cl. apropos.el, auto-save.el, buff-menu.el, cl-extra.el, dragdrop.el, faces.el, files.el, fill.el, font-lock.el, font.el, gtk-faces.el, gui.el, help.el, hyper-apropos.el, info.el, isearch-mode.el, keymap.el, lisp-mnt.el, mouse.el, package-admin.el, package-get.el, printer.el, process.el, resize-minibuffer.el, simple.el, toolbar-items.el, wid-edit.el, win32-native.el: fix warnings. very-early-lisp.el: update docs. mule\chinese.el, mule\japan-util.el: fix warnings.
