Okay, I now see that I introduced that problem myself back
in November 2007; eqn produces a \^ where it should produce
a \|. I'll find a way to make that work properly and tell
you when it's done.

That's what the geqn manual page describes in its usage
section as "automatic spacing", at least. I never looked
into its source code so I cannot tell you how much of a
difference it actually makes.

I see, I was wrong, it actually needs -mg (the groff
compatibility macros) to work.
