Thanks, I think people who use line-spacing in Calc stack window, or
otherwise change the default height of a window-line, should know what
they are doing and what would be the result.

I installed the change to use the 'floor' argument to window-height,
and I think this works well enough in the "usual" use cases;
everything else would be a non-trivial enhancement.  So I'm closing
this bug.
