This is because we always are dealing with diff lines, not real lines.
So there is always a ' ', '+', or '-' in character 0 of the line (within
a diff hunk).  In some tests we may be looking at either context ' '
or new lines '+' and so its handy to use '.' over '[ \+]', and I have
maintained that model throughout the other tests.
