problem with object names containing "//"

[Dave Matthews]

Hi Keith,

Thanks for sending me back to the testing bench.  Actually it's neither. (!)
It's the trailing single slash at the end of the object name.

The following causes the problems in sgifaceserver and tace that I reported
before:  
acedb at www.graingenes.org> find reference bob/

Further information:

1. The problem occurs whether "bob/" is in the database or not.

2. The following variations work fine (including give the correct results
if the object is in the database):
acedb at www.graingenes.org> find reference bo/b 
acedb at www.graingenes.org> find reference "bob/"
acedb at www.graingenes.org> find reference "bob\/"
acedb at www.graingenes.org> find reference "bo/b"
acedb at www.graingenes.org> find reference "bo\/b"

3. The following variations don't cause the server to crash, but they don't
find any objects:
acedb at www.graingenes.org> find reference bob\/
acedb at www.graingenes.org> find reference bo\/b

Apologies for not analyzing the problem properly in the first place.
