Details:

In the manual page 228 or around, we read: 

If the Octave:possible-matlab-short-circuit-operator warning is
enabled, Octave will warn about using the not short circuiting operators &
and | inside if or while conditions. 


I feel, one should mention that this warning 
is to make clear, that in if and while conditions 
& and | behave like && and || and shall thus be replaced by 
explictly && and ||. 
This is for matlab compatibility. 
As matlab does not support until statements, 
octave treats & and | in until conditions 
regularly without shortcut.
