Re: [PATCH v5 1/2] git-prompt.sh: if pc mode, immediately set PS1

> At the beginning of __git_ps1, right after determining that the
> function is running in pc mode, set PS1 to a plain (undecorated)
> prompt.  This makes it possible to simply return early without having
> to set PS1 if the prompt should not be decorated.
