Comment:

 Hmmm, still not sure about this.  The documentation now states:
 {{{
 \Z Matches a zero-width assertion consisting of an optional sequence of
 newlines
 at the end of a buffer: equivalent to the regular expression (?=\v*\z).
 }}}
 However, a few lines earlier, we have:
 {{{
 a "buffer" in this context is the whole of the input text that is being
 matched
 against.
 }}}
 In that case, shouldn't my sample code above result in "1\r2A" rather than
 "1\r2A\rA\rA"?
