Running `git fetch <remote>` in git 1.8+ outputs nothing to STDOUT or STDERR if the remote is up-to-date. By changing the fetch command to use --verbose, we ensure something is always output when git fetch runs, even if the remote is up-to-date. This will prevent the IO.pipe from hanging when executing the git fetch command.

Now the handling of sub-processes is abstracted away, and we can wait for, read and handle the exit status of the process more deterministically.
