Aha, it was assumed that the user types
"eclear" and hits RET, but OK, now it should
work as an arbitrary command as well:
(defun eclear ()
(interactive)
(goto-char (point-max))
(let ((inhibit-read-only t))
(delete-region (point-min) (point-at-bol)) ))
Perhaps too arbitrary BTW - perhaps one should
add a guard that confirms that the mode is
EShell, because otherwise one could get used
to it (to invoke it like any command, not type
"ecelar" and hit RET) and then by mistake
"clear" some other useful buffer that way.
