Myself included -- the default value tends to give me a full-screen
control frame entirely obscuring the original frame, which is very
unhelpful indeed.

That problem aside, I've observed that creating a separate GUI
frame can be *significantly* slower; so for me the plain option
is a win for performance as well as usability.

As `ediff-setup-windows-plain' is the faster and the most reliable
option across differing kinds of windowing systems, I am strongly
in favour of changing the default `ediff-window-setup-function'
value to that.

Users who prefer the separate frame can easily make that change in
their configs easily enough, and improvements to better support a
separate control frame can of course still go ahead.
