Remove "Show that the message has been edited"

[Heosforo]

Hello guys.
How can I remove this field?, I've searching on templates but couldn't find anything yet.

Thanks in advance.

This option should not show, if you disable "Can edit silently?" for that usergroup  in your ACP - Members - Groups - (Usergroup) - Content

Thanks mate
I did not know the existence of this, I have long wanted to remove it.
