It seems I made an off-by-one error in my last patch for multiple
locations. This only affected the position of the caret character,
which we don't test (since the testsuite uses
-fno-diagnostics-show-caret). Fixed thusly and added a comment to
remind me and others that locations start at 1, but we still want to
start at 0 (but not start at 0 and add an extra space like I did
before).

Cheers,

Manuel.
