WYSIWYG \prime problems

[Dan Mueth]

The \prime character appears too high if used in the exponent, as one
would normally do in an equation: $x^\prime = x^2$ produces nice
postscript output, but looks poor in Lyx.  (This is true independent of
whether one types "\prime" or uses the Math Panel.)

In Lyx, the prime character looks good if you do $x\prime=x^2$, but of
course the postscript output then looks wrong.
