Summary: Strange behaviour of nargout

Release: 3.6.3
Operating System: GNU/Linux
_______________________________________________________
Details:
There is an option of nargout to call it with the name of a function, and then
it returns the number of optional output arguments of that function. However,
if that function has not been called before in the current Octave session,
nargout will fail to find the function.
Steps to reproduce:
In a freshly started Octave, type:
octave:1> nargout("sombrero")
error: nargout: invalid function
-verbatim
Calling the sombrero function and trying again fixes the problem:
octave:1> sombrero
octave:2> nargout("sombrero")
ans = 3
I am using Octave 3.6.3 on x86_64-redhat-linux-gnu
I think this is related to the work discussed here:

Cheers,
