Subject: bash-completion now loads completions dynamically, so __git_ps1 is not defined when you open a shell
Message-ID: <CANaWP3wu3260uFNzCLJ=YSG1BWFr=ge_6CmMGrG6zLThvFnjcQ@mail.gmail.com>

The __git_ps1 function is defined in same script that defines Git's
tab completions (contrib/completion/git-completion.bash). Since
bash-completion loads completions on-the-fly in newer versions, the
__git_ps1 function isn't immediately available in a new shell. How
should this be handled? Should users just source git-completion.bash
before they redefine $PS1?
