I have just upgraded git. It's now a symlink to the Cellared most recent version.
$ ls -l `which git` /usr/local/bin/git -> ../Cellar/git/2.14.1/bin/git
$git --version git version 2.11.0 (Apple Git-81)
Do I have two different versions installed at once? How can I clean up the remnants of the Apple Git-81 version?
