mvar with document() fails to append

[philshafer]

( Originally http://code.google.com/p/libslax/issues/detail?id=8 )

What steps will reproduce the problem?
1. run "test-count-05.slax" test case
2.
3.

version 1.1;

var $last = document("test-count.xml");
mvar $one = $last/in;
mvar $two = $last/in/node();

match / {
    <top> {
    <one> {
        <before> { copy-of $one; }
        append $one += <new> "one";
        <after> { copy-of $one; }
    }
    <two> {
        <before> { copy-of $two; }
        append $two += <new> "one";
        <after> { copy-of $two; }
    }
    }
}

What is the expected output? What do you see instead?

Neither of the append operations work.

The <new> is added to $slax-one, but not to $one:

(sdb) p $slax-one
[node-set](1) rtf-doc
<in>
  <one>1</one>
  <two>2</two>
  <three>3</three>
  <four>4</four>
  <five>5</five>
</in>
<new>one</new>

(sdb) p $one
[node-set](1)
<in>
  <one>1</one>
  <two>2</two>
  <three>3</three>
  <four>4</four>
  <five>5</five>
</in>
