Ok. I do not see it with octave 3.0.5 -- again fwiw

I know that. Using different font does not seem to help. To get the fonts
to an acceptable size in eps, I need to set their size to 24 that
makes x11 plots
look grotesque. Again this is definitely change with 3.2.2 vs 3.0.5.
I am using both on the same computer with the same gnuplot.
It appers to me that with 3.2.2 the size of picture in eps has increased
but fonts remein the same, so the fonts _for the given picture size_
become too small.

I have this problem while running "./run-octave --no-init-file" in the
top level source-tree directory. So octave uses defaults.
The postscript prolog has BoundingBox defined as:

%%BoundingBox: 50 50 612 792

If I change it to

%%BoundingBox: 0 0 612 792

I get standard letter-size page and the figure looks about right.

(A4 pagesize would be 595 848, if I remember correctly)
