| Repeat-By:
| ---------
| 
| octave:58> is_bool( true | true )
| ans = 0
| octave:59> is_bool( true & true )
| ans = 0
| octave:60> is_bool( true || true )
| ans = 0
| octave:61> is_bool( true && true )
| ans = 0

| Not a real fix, but a work-around:

A real fix is already in the current CVS sources.
