From baf5aaa33383af656a34b7ba9039e9eb3c9e678c Mon Sep 17 00:00:00 2001 From: René Scharfe Date: Fri, 6 Jan 2012 18:13:00 +0100 Subject: xdiff: print post-image for common records instead of pre-image Normally it doesn't matter if we show the pre-image or th post-image for the common parts of a diff because they are the same. If white-space changes are ignored they can differ, though. The new text after applying the diff is more interesting in that case, so show that instead of the old contents. Note: GNU diff shows the pre-image.
