Note in delta an incompatibility for \cX

X in "\cX" must now be ASCII.  Previously, it could be anything, but led
to a malformed utf8 error if wasn't Latin1.  This construct was never
intended to be used for anything but (a subset of) ASCII.

(moved to the delta for 5.13.1)

+=head2 "C<\cI<X>>"
 
+The backslash-c construct was designed as a way of specifying
+non-printable characters, but there were no restrictions (on ASCII
+platforms) on what the character following the C<c> could be.  Now, that
+character must be one of the ASCII characters.
