 Bug in handling of "\Z"

 According to the documentation, the RE "\Z" is equivalent to "\n*\z", but
 it behaves differently.  Given the text:

 {{{
 1\r
 2\r
 \r
 }}}

 Replacing all instances of "\n*\z" with "A" correctly results in:

 {{{
 1\r
 2\r
 \r
 A
 }}}

 Whereas replacing all instances of "\Z" with "A" incorrectly results in:

 {{{
 1\r
 2A\r
 A\r
 A
 }}}

 It does not seem to differentiate between "\r" and "\n", nor to correctly
 recognize the end of the buffer.
