-   Usage and known bugs:
-   Terminal key codes are not extensive, and more will probably
-   need to be added. This version was created on Debian GNU/Linux 2.x.
-   Delete, Backspace, Home, End, and the arrow keys were tested
-   to work in an Xterm and console. Ctrl-A also works as Home.
-   Ctrl-E also works as End.
-
-   Small bugs (simple effect):
-   - not true viewing if terminal size (x*y symbols) less
-     size (prompt + editor's line + 2 symbols)
-   - not true viewing if length prompt less terminal width
