Homebrewのemacsをeditしてインラインパッチなどを当てる（Emacs-24.3）

『Homebrewのemacsをeditしてインラインパッチなどを当てる（Emacs-24.2）』を書いてしばらく経ちましたが、その後Emacs-24.3対応のFormulaが出ました。幸いにしてよくまとまったEmacs 24.3への日本語環境用のパッチがgistにありましたので、今度はそれを使います。

ビルドは今回もSuperenvを回避して行いました。

==> Caveats
Emacs.app was installed to:
  /usr/local/Cellar/emacs/24.3

 To link the application to a normal Mac OS X location:
   brew linkapps
 or:
   ln -s /usr/local/Cellar/emacs/24.3/Emacs.app /Applications

 A command line wrapper for the cocoa app was installed to:
  /usr/local/Cellar/emacs/24.3/bin/emacs
Because the official bazaar repository might be slow, we include an option for
pulling HEAD from an unofficial Git mirror:

  brew install emacs --HEAD --use-git-head

There is inevitably some lag between checkins made to the official Emacs bazaar
repository and their appearance on the Savannah mirror. See
http://git.savannah.gnu.org/cgit/emacs.git for the mirror's status. The Emacs
devs do not provide support for the git mirror, and they might reject bug
reports filed with git version information. Use it at your own risk.

Emacs creates an executable `ctags` that stomps on exuberant-ctags. In
order to prevent that, we remove `ctags` and its manpage from the emacs
build before linking. (Add the flag "--keep-ctags" to keep it.) You can
install exuberant-ctags via brew with `brew install ctags`.
(exuberant-ctags can provide both vim-style and emacs-style tags.)

しかしながら、以下のようなコードがemacs.rbにあったので、ひょっとしたらsuperenv回避の必要はないかもしれません。

emacs.rb

  if build.head? or build.include? "cocoa"
    depends_on :autoconf
    depends_on :automake
  end
