Emacs

Hi,

I have been using this emacs plugin for several months. Now that `require_tool' script has been added, I guess it is time to come before you with this new one.

Here is a copy/paste of `emacs.plugin.zsh' header:

Emacs 23 daemon capability is a killing feature. One emacs process handles all your frames whether you use a frame opened in a terminal via a ssh connection or X frames opened on the same host.

Benefits are multiple
- You don't have the cost of starting Emacs all the time anymore
- Opening a file is as fast as Emacs does not have anything else to do.
- You can share opened buffered across opened frames.
- Configuration changes made at runtime are applied to all frames.


It provides aliases, helper functions, and set EDITOR environment variable.

Best regards and thank you again for this repo.
