When doing a combined diff, we did not respect textconv attributes at all. This generally lead to us printing "Binary files differ" when we could show a combined diff of the converted text. This patch converts file contents according to textconv attributes. The implementation is slightly ugly; because the textconv code is tightly linked with the diff_filespec code, we temporarily create a diff_filespec during conversion. In practice, though, this should not create a performance problem. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
