Re: [PATCH] rev-parse --show-prefix: add in trailing newline

But it will break existing scripts if they expect the following to work:

Huh?  I tried this:

	$ foo="$(printf '\n')/bar"
	$ printf '%s\n' "$foo"
	/bar

If that didn't work, it would mean that "git rev-parse --show-prefix"
would never work when the prefix is nonempty, because it is followed
by a newline.
