I suppose .ofig is fine for the files we generate.  I checked in this 
change:

  http://hg.savannah.gnu.org/hgweb/octave/rev/92acdcf72c46

If we ever generate files that could be opened with Matlab, then maybe 
we could switch to .fig (possibly with a configuration option to choose 
the default suffix?).

I'll take a look at it.

OK, it seemed to work for me.  But maybe I was saving figures that did 
not have listeners, or that were not important for the simple thing I 
was doing (just loading and viewing a figure).
