evil-qemacs/qe.h
Charlie Gordon 811a16a0e3 changed do_line_numbers to do_toggle_line_numbers 
changed do_line_truncate to do_toggle_truncate_lines
fixed define_kbd_macro string arguments mixup
added edit_find() to locate window with a given buffer
removed test kludge in term_flush()
various cosmetics.
