- update to 21.4 movemail vulnerability release
    - no longer need movemail-CAN-2005-0100.patch
    - replace %{_bindir}/emacs alternatives with a wrapper script (Warren
        Togami) to prevent it from disappearing when upgrading (Michal
        Jaegermann, 154326)
    - suffix the X emacs binaries with -x and the no X binaries with -nox
    - the wrapper script %{_bindir}/emacs-%%version runs emacs-x if installed
        or otherwise emacs-nox. %{_bindir}/emacs is a symlink to the wrapper
    - make emacs and emacs-nox own the subdirs in %{_libexecdir}
    - add a bunch of fixes from debian's emacs21_21.4a-1 patch:
        battery-acpi-support.dpatch, bzero-and-have-stdlib.dpatch,
        coding-region-leak.dpatch, detect-coding-iso2022.dpatch,
        fix-batch-mode-signal-handling.dpatch, pcl-cvs-format.dpatch,
        python-completion-ignored-extensions.dpatch,
        remote-files-permissions.dpatch, save-buffer.dpatch,
        scroll-margin.dpatch, xfree86-4.3-modifiers.dpatch
    - add fix-x-vs-no-x-diffs.dpatch
    - define emacs_libexecdir
    - build both emacs and emacs-nox as %%{version}.1 and move common DOC file
        to emacs-common
    - suffix version in fns-%%{version}.1.el with -x and -nox respectively
    - add 100 to elisp patches
