+
+ * vc.el Add new optional BUFFER argument to vc-BACKEND-print-log
+ and vc-BACKEND-diff.
+ (vc-print-log): If the print-log implementation supports it, use
+ the new BUFFER argument to direct output to *vc-change-log*, not *vc*.
+ (vc-version-diff, vc-diff-internal): Doc fixes.
+
+ * vc-hooks.el (vc-default-workfile-unchanged-p): If the
+ implementation supports it, let diff output go to *vc*,
+ not *vc-diff*, since this is an internal call.
+
+ * vc-cvs.el (vc-cvs-print-log, vc-cvs-diff): Add optional BUFFER
+ argument.
+
+ * vc-rcs.el (vc-rcs-print-log, vc-rcs-diff): Likewise.
+
+ * vc-sccs.el (vc-sccs-print-log, vc-sccs-diff): Likewise.
