Suppress the 'Fatal: not a git repository' errors

[justinas]

This one command was not silenced and caused the mentioned error when the working directory is not a git repo.

Thank you for this. Any chance you can write a test for it? Or give me a run down of the conditions you saw it cause an issue? Then I can write the test myself.

Thanks 🙇

Happens on OS X Yosemite with zsh. Starting a new shell in a directory that's not a Git repo (or cd-ing into one later, for that matter) prints out the error message for every new line of the shell.

Odd, the is_repo check is meant to prevent that from being called.

I'll merge but that hasn't happened from me using this for over a year personally. Hmmm, smells of an underlying issue in is_repo or dot_git function.
