(te-terminal-name-prefix): Change from

"emacs-virtual" to "emacs-em", so that things will work on systems
which allow only short terminal-type names.
(terminal-emulator): Delete the hyphen between
te-terminal-name-prefix and the width and height of the window.
(te-create-terminfo): Reformat the terminfo entry slightly.

(te-terminfo-directory): New variable.
(te-create-terminfo, te-tic-sentinel): Use te-terminfo-directory.
