xdiff: print post-image for common records instead of pre-imagers/diff-postimage-in-context
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.
