An attempt to quit difftool by hitting Ctrl-D (EOF) at its prompt does not quit it, but is treated as if 'yes' was answered to the prompt and all following prompts, which is contrary to the user's intent. Fix the error check. Signed-off-by: Johannes Sixt <j6t@kdbg.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
