Can that be site-start.el?

I added it to site-start.el.  It takes effect.  I don't like it
maximized, though.  I just wish it'd stick to the height of the initial
frame, which I set with -fh on the command line.

I looked up the manual and came up with

  (add-to-list 'default-frame-alist '(height . 0.90))

where 90% is about right for me, but this has the side-effect that the
initial-frame is not full-height any longer, that is, this undoes the
order given by -fh on the command line.
