We ignore the option --color-moved if an external diff program is configured, presumably because its overhead is unnecessary in that case. Respect the option if we don't actually use the external diff, though.
Reported-by: lolligerhans@gmx.de Helped-by: Junio C Hamano <gitster@pobox.com> Signed-off-by: René Scharfe <l.s.r@web.de> --- Changes since v1: * use single word colors, leaving the background unchanged, as they are easier to read, * run git diff to generate the expected content instead of reusing the output of the previous test ... * ... and put the common arguments in a variable to make clear that we compare diff with and without a diff.external/--no-ext-diff dance, * use echo instead of false as the (unused) external diff command to avoid giving the wrong impression that diff.external is a boolean option we turn off here.
