I'd find this rather annoying. :)

My understanding is that the application should be responsible for
specifying desired aspect ratio, using the XSizeHints structure fields
named {min,max}_aspect.{x,y}. ratpoison has code to handle this since
version 1.4.0.  A quick look at the gnuplot source (version 4.4) tells
me that gnuplot doesn't use this to manage the window size.

Maybe you should report this problem to the gnuplot developers (if no
one hasn't done so before)?
