Emacs fuzzy git-grep(1).
M-x anything-git-grep
In your emacs config:
(add-to-list 'load-path "~/.emacs.d/load/path/anything-git-grep.el")
(require 'anything-git-grep)
There is no need to setup load-path with add-to-list if you copy
anything-git-grep.el
to load-path directories.
You will need to install anything-mode. See documentation for how to install.
