[Octave-bug-tracker] [bug #49794] display vs. disp functions

[John W. Eaton]

Follow-up Comment #30, bug #49794 (project octave):

I made an additional change so that Octave never calls the display function
with more than one input argument since this is not documented Matlab behavior
and it was causing trouble for existing Octave classes.  It might be possible
to check whether a display function for a class is defined to accept one or
two arguments and call it differently based on this determination, but I opted
against that since this feature is undocumented in Matlab.

I modified the documentation for the built-in display function so that it
doesn't mention the two-argument version, but I left it as before so that
things like


display (1, 'foo')


will work (as they do in Matlab).

I'll fix any display methods in Octave so that they use inputname instead of a
second argument.

Here's the changeset:
