path: octave 3.0.0 can't find itself

[Dushan Mitrovich]

I've been using Octave 2.9.15 on a Mac (Intel) under X.4.11.  When Octave
3.0.0 became available a few days ago I decided to update my installation
to it.

Not wanting to dump the old older app, residing in /Applications, until I
had a chance to test the new one, I renamed the old one Octave-2.9.15.app,
then dragged the new Octave.app from the .dmg file to the /Applications
folder.  I expected to have to tell the new one the path to search for my
personal script files and functions.

Instead, when I open the new Octave.app it announces

  warning: addpath: /Applications/Octave.app/Contents/Resources/share/...
                    octave/2.9.15/m/<filename>

where as in Octave '...' denotes continuation, and '<filename>' refers to
different files.  To the command 'path' the respond is

  /Users/dushanm/Octave
  /Applications/Octave.app/Contents/Resources/share/octave/site/m/
  /Applications/Octave.app/Contents/Resources/share/octave/site/m/startup

So from somewhere it got correct information about the path to my personal
files (the first reference), but wrong information about other paths.

I looked everywhere on my system for some file that refers to '2.9.15' and
found exactly 5 files, 4 of them in ~/Trash, with that reference.  In each
case it was in a comment line.  Where in the world is Octave getting all
this information, much of it wrong?  First I'd like to understand this, and
second I want to correct it.
