Sorry about that.

63 is the exact number of lines I can put in a buffer when
gnome-terminal is maximized on the computer where emacs is running.
If I run gnome-terminal on my laptop (from which I was ssh'ing when the
crash happened), I count 22 lines at the default window size, and 41
when the window is maximized (window, in the "X window" sense).
