>Description:
The man page for su(1) says the following:
     "-c class
             Use the settings of the specified login class.  The login class
             must be defined in login.conf(5).  Only allowed for the super-
             user."

However su actually treats the argument to -c as a command and runs it as the target user.

The actual behavior is describe correctly in the EXAMPLES section.
