run 'git status' when another git command fails with 'fatal: not in a…

… git directory'

'git status' prints a more informative error message than other git
commands in certain failure scenarios, specifically including when the
workspace is not owned by the user executing 'git'. Hopefully printing
this extra error message will make it more obvious to operators what is
going on if they encounter this kind of failure.
