It seems so. I've compared the distances of the equations
x = y + z
and
x~=~y~+~z
in the original eqn2e.ps documentaion file `Typesetting Mathematics --
User's Guide (Second Edition), page 1 and 2.
The tilde characters before and after the equal sign cause no effect
in the output; only the tilde characters before and after the `+'
increase the spacing (by 0.6 PS points each, which is almost
invisible). groff does exactly the same.
