I've been throwing out the child with the bathwater.  Please try the
attached patch which retains an important conjunct.

The major purpose of 'frame-inhibit-implied-resize' is to avoid resizes
when a frame has been tailored to fit into some arrangement of windows
on the display as, for example, with a tiling window manager.  Here I
hardly ever use it.  By design, it should have no effect when making a
new frame which is what the corrected patch should support.  Still, it
might not work for elements like the external tool bar.

Let's.
