Strictly speaking this change was not necessary. "< requested.txt" already redirects
input from the requested.txt file, just as "cat requested.txt |" does. I doesn't
matter that "< requested.txt" is at the beginning of the line in this case.

I won't revert your change, though, because we had a couple of people that either
thought putting "< requested.txt" at the beginning of the line was illegal and that
the command must have been wrong, and consequently mangled it to a state where it
no longer worked.

While this is a useless use of cat, I'll allow it.
