[Octave-bug-tracker] [bug #64516] Document how optimset expands short option inputs to full option names

[Liang Tang]

Follow-up Comment #16, bug #64516 (project octave):

Rik, 

I briefly revisited the optimset.  This shows what I think I did wrong.  The
right or better way seems to be 

options=optimset('fmincon'); 
options=optimset(options, 'nxxx', 100); 

options=optimset();  will bring up a superset of (useless) fields that
potentially mess up something.  You might want to try in matlab on this.  

My past experiences with this type auto appending or conversion do suggest
that there are some min number of characters, like three or four, before the
software takes over.  So I wasn't ready for running into this with a single
character.  I knew a single character field is a bad idea, not a good
practice. Thanks.
