visudo doesn't show error message

[thouters]

I added a line to the sudoers file with "sudo visudo"
when I exited vim, I was presented with this options menu, but never
saw a message that the config I wrote is corrupt! I ignored the DANGER
because I *asumed* (my bad) that the authors are paranoid about saving their config file.

thomas@thomas-VirtualBox ~ % sudo visudo
[sudo] password for thomas:
(... editting)
(I ran a which openocd command from vim, thus the next lines)
[No write since last change]
/usr/bin/openocd

Press ENTER or type command to continue
(editting... :wq)
What now?
Options are:
  (e)dit sudoers file again
  e(x)it without saving changes to sudoers file
  (Q)uit and save changes to sudoers file (DANGER!)
