Currently, this is not configurable from ifeffit.  In fact, I
think this is the default spacing for PGPLOT:  I don't have
'throw away 25% of the area' hard-wired in!  It's possible
that this could be changed, but I'd have to look into it.

On the other hand, PGPLOT is pretty awful and it might not be 
worth trying to fix it....

'reset' is intended to reinitialize the plotting color and
symbol tables and restart the plotting device. I think it's
been broken, probably for awhile.  I'll look into fixing it.

'key=""' is supposed to cause no key to be written.  But it
appears that this is not working correctly either!!!  I'm
pretty sure this used to work.  It probably gotten broken in
1.0076.  At first pass, it looks easy to fix.

I hope (really! a month of beamtime will end Sunday!) to have
a new version late next week or early May with several bug
fixes and improvements, including ebinning of mu(E) data
during background subtraction, correct FTs from feffit() for
data on a kgrid=/=0.05, these plotting fixes for sure, and
hopefully multiple-k-weights in feffit(), a rebin() command,
improvements to diffkk() and probably a few other things...
