I just realized that the initial term-height didn't use floor to round
down the value of window-text-height.  This was masked by a hook I have
in my configuration.  I attached another patch that fixes the issue.

Subject: [PATCH] Consider line spacing and font height when deriving proc
 window size

* lisp/window.el (window-adjust-process-window-size): Use
  window-screen-lines instead of window-body-height.
* lisp/term.el (term-mode): Use window-screen-lines to set the initial
  window height.
