In the Octave-Forge financial package, isbusday() includes some extra holidays
when the datenums passed into the function are not integer values. 

To replicate:

octave:51> n1=now-100;
octave:52> n1=now-600;
octave:79> sum(isbusday(n1:n2))
ans =  357
octave:80> sum(isbusday(floor(n1):floor(n2)))
ans =  345

As a fix for my local copy, I modified line 50 to be 

mask = mask | ismember(floor(rd), hol); % I added the floor()

Since hol contains only integer values and rd might contain non-integer values
(that should be equivalent holiday-wise to integer values).
