This is related to
http://www.octave.org/octave-lists/archive/help-octave.2005/msg00070.html
(that is why I x-posted to the "help" list, though the discussion should be
in the "bug" list)

The command line for splot:

sp '/tmp/oct-quoAnd' u 1:2:3 t "line 1"

is wrong for the data file (it has only one column of data, hence "1:2:3" format is wrong)
I do not know what has changed: data file format, or code that generates
the command line for gnuplot...

It is definitely a bug.

Sorry for not being more helpful.

Dmitri.
