Details:

This is Debian bug 731992,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=731992, reported by Kacper
Gutowski which I am forwarding here.

===============================
hyper% octave -q --no-init-file
warning: function /usr/share/octave/packages/statistics-1.2.2/fstat.m shadows
a core library function
octave:1> princomp(rand(10,2))
error: 'r' undefined near line 103 column 48
error: invalid limit value in colon expression
error: evaluating argument list element number 1
error: called from:
error:   /usr/share/octave/packages/statistics-1.2.2/princomp.m at line 103,
column 9
octave:1>

As far as I can tell this is a trivial bug caused by the fact that 'r' is only
calculated if nargout > 1 and not needed otherwise so it can be fixed with the
simple patch attached.
===============================
