FWIW, here the results of the commands in comment #1 in Matlab R2016a:

>> or([])
Error using  |
Not enough input arguments.

>> not([])

ans =

Besides, if these binary functions would not accept only one argument, then the statement "At least one argument is required" in their docstrings had also to be removed or updated.

As a start, I checked in a change that produces an error if or() or any other binary function is called with just a single argument.  See this changeset http://hg.savannah.gnu.org/hgweb/octave/rev/308a272bbe3c.

Could you check in Matlab if there is a special exception for empty inputs by testing

or ([])

Also, what does this return?

not ([])

It might [], or it might be 1 since [] could be seen as false.

>> or(1:10)
Error using  |
Not enough input arguments.

Where in Octave,

>> or([1:10])
ans =

    1    2    3    4    5    6    7    8    9   10


It should have produce error,because we are providing only
or(X) [But help says,or(X,Y)].
And here output is definitely wrong,It should have 1.
