Git commits from Emacs

I've always hated switching to vim every time I want to write a commit message. And Emacs (the obviously superior editor) always takes too damned long to load with my crazy .emacs file. So I did a little digging and came up with this.

First add a minimal .emacs file (call it .emacs.minimal and put it in your home directory):

;; taken from http://snarfed.org/minimal_emacs_for_fast_startup
; cutoff for word wrap
(setq-default fill-column 79)

; F12 toggles auto-fill mode
(global-set-key [f12] 'auto-fill-mode)

; C-- keybinding for undo (removes the shift)
(global-set-key [(control -)] 'undo)

; turn on pending delete (when a region
; is selected, typing replaces it)
(delete-selection-mode t)

; when on a tab, make the cursor the tab length
(setq-default x-stretch-cursor t)

; avoid garbage collection (default is only 400k)
(setq-default gc-cons-threshold 4000000)

; turn on random customization options
(custom-set-variables
  '(sentence-end-double-space nil)
  '(truncate-partial-width-windows nil)
  '(line-number-mode t)
  '(column-number-mode t)
  '(query-user-mail-address nil)
  '(visible-bell t))

Then add in your ~/.gitconfig file add these lines:

[core]
    editor = emacs -nw --no-init-file --no-site-file --load ~/.emacs.minimal

And now you should be able to edit config files with the best damned editor and minimal startup time. You're welcome.

An alternative is to let Emacs started up all the time (for me it's not a constraint as I do almost all my work inside anyway) and map the emacs command to "emacsclient" , as Emacs supports a server/client operation mode (EDITOR=emacsclient in your .bashrc, for example).
