Small patch to "clear" to add flush

[JoSH Lehan]

Hello.

I have made a small one-line patch to the "clear" applet, to ensure
that output gets flushed.
It's a workaround for that well-known bug in glibc:

http://sources.redhat.com/bugzilla/show_bug.cgi?id=3400

Also, I changed the clear string to output 7 characters, not 6, just
to be correct with respect to the traditional terminal codes.

Here's the patch:

 }

Comments/suggestions?
