Check that git-wad is not running in a .git dir

Some versions of git return an error when "git rev-parse" is executed in
a git directory, but others do not. Letting git handle the error when it
queries the working directory is therefore not sufficient: no error
could be reported when git-wad should not be executed from the current
directory. Hence this commit, which explicitly checks the current
directory before executing the git-wad command.
