diff-no-index: exit(1) if 'diff --quiet <repo file> <external file>' finds changes
When running 'git diff --quiet <file1> <file2>', if file1 or file2 is outside the repository, it will exit(0) even if the files differ. It should exit(1) when they differ. This happens because 'diff_no_index' looks at the 'found_changes' member from 'diff_options' to determine if changes were made. This is the wrong thing to do, since it is only set if xdiff is actually run and it finds a change (the diff machinery will optimize out the xdiff call when it is not necessary) and in that case HAS_CHANGED flag needs to be taken into account. Use diff_result_code() that knows all these details for the correct exit value instead. Signed-off-by: Tim Henigan <tim.henigan@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
