Details:

Input:

issorted([])

Output:

error: issorted: needs a vector
-varbatim-

It appears to me as "an error message for valid input", so I figure it is a
bug. I would expect the result to be TRUE, as in Matlab. Even if Octave had
reasons to depart from the latter convention, I would expect issorted to
accept the empty vector.
