	file input focus vulnerabilities

Oh! I was wrong. I didn't see file1's value is
assigned to text1's value.

certainly, it is a flaw as nicely explained by
Zalewski.

I wrote a PoC myself and found that it's not necessary
to put focus on the label. focussing the file input
also works. I succeeded in writing the same PoC
without label with minor modifications.
