Disallow working directory commands in a bare repository.
If the user tries to run a porcelainish command which requires
a working directory in a bare repository they may get unexpected
results which are difficult to predict and may differ from command
to command.
Instead we should detect that the current repository is a bare
repository and refuse to run the command there, as there is no
working directory associated with it.
