system command status/output order changed in 2.9.x

[Joshua Rigler]

After a brief search, I could find no mention of this change in the last 
year's email list archives (as saved on my computer), nor by pointing 
Google at the standard Octave websites (including the wiki).

The output order of Octave's 'system' command seems to have changed 
since 2.1.x.  It used to be:

> [output, status] = system(sys_cmd);


It is now (in 2.9.8):

> [status, output] = system(sys_cmd);


It seems to me that this warrants a note in the new 'NEWS' file 
(distributed in the source code tar-ball or via CVS), along with all the 
other changes due in Octave 3.x, since it could very easily change the 
behavior of an existing program without actually breaking it.  For now, 
I've tried to structure this email so that it might easily be found 
using standard search engines on the Octave mailing list archives, just 
in case somebody else encounters this issue.  Sorry for the distraction.
