Summary: XQ: "Zombie" document in collection
Initial Comment:
[Jun 2008 release]
A deleted document from a collection where there is more than 1 document is
still visible using the collection("mycoll") function.
On Feb 2008 release, the pf:collection function worked correctly, but not the
fn:collection function, that produced the same bug.
Stefan reproduced this bug, giving the following trace :

The problem seems to be "even worse":
* add 2 documents to a single collection "MyCol"
* delete one of them, again
=> + pf:colections(), pf:documents(), & pf:documents("MyCol") correctly
show only one remaining document
- pf:collection("MyCol") & fn:collection("MyCol") wrongly show both
documents
* stop Mserver
* restart Mserver
=> - all above functions wrongly show *both* documents, again!
This happens both with the (now) default Algebra back-end and with the
(old) "milprint_summer" back-end.
