Actually, even "C:\my-dir" is unnecessary.  The reason I couldn't at
first reproduce it is that I tried that in a normal optimized build.
But the xassert that aborts is only compiled under -DENABLE_CHECKING.

I think this happens because w32 lacks a proper implementation of
get_tty_size.  So the new frame starts with bogus dimensions 10x10,
and then the height gets incremented by 1 due to the menu bar, which
triggers the abort.
