I don't know which libraries are needed to build with Lucid.  I
installed open motif libraries but the build script doesn't appreciate
them.  So I can't test these here.  At least the "subsequent frames"
look correct.

This can be fixed here using the attached patch.  But with a frame width
of 60 the echo area should resize but disappears on the initial frame.
I don't yet know why.
