You can't clear an environment variable from a parent process (shell). This is 
simply not possible.

Check this schema

bash (env0)
  yast2 (env0.1)
    yast2-doSomething (env0.1.1)
  zypper (env0.2)

 
Whenever you spawn a child process, the environment from the parent is copied 
and that's the only environment you can modify. So if yast-doSomething
would clear the http_proxy, that would be completely useless for a later start 
of zypper, as it will copy env0 again and create 0.2... so no go at
all...
