non-unified diffs. Some functionality moved into `diff-hunk-text' and `diff-find-text'. Add OTHER-FILE, DRY-RUN, POPUP, and NOERROR arguments. If DRY-RUN is true, don't actually modify anything. Only reposition point in the patched file if the patch succeeds. Only pop up another window if POPUP is true. Emit a message describing what happened if successful, and at what line-offset. Automatically detect reversed hunks and do something appropriate. (diff-hunk-text, diff-find-text): New functions. (diff-filter-lines): Function removed. (diff-test-hunk): New function. (diff-goto-source): Rewritten in terms of diff-apply-hunk.
