    _______________________________________________________

Details:

This is just a small nit.  When you use the who command, and there are no
variables in the present scope, it still prints a summary line and three
newlines.

Steps to reproduce:


clear all
who
Variables visible from the current scope:



octave:4> 


Matlab doesn't bother to print anything and just advances the command counter.
 I think Octave should do the same.
