Edit GIT runtime information
This should be the action after Move EmacsConfig from Dropbox to GIT - Shammerism.
Change Editor
$ git config --global core.editor "/Applications/Emacs.app/Contents/MacOS/Emacs -nw"
On my Mac, this should be defined with full path. If determined just "emacs", it will be failed to run.
Change Committer information
GIT generates automatically committer information based on the current login user account on the host and it's hostname. This information can be edited by "git config --global --edit" and edit it.
