I'm not quite sure if this is a good idea... the curl documentation
states that curl will re-use the same TCP connection when it can, so
you'll get kind of skewed results. What are you trying to measure
anyway? It seems to me that one file would be enough to measure
webserver responsiveness, and if you're trying to measure the bandwidth
of the connection (to see if it's saturated or something), you'd
probably be better off with big ICMP packets.

That said, here's a patch that makes multiple URLs (whether in the 
[]/{} notation or with separate arguments) possible. It needs
the 'redirect' patch I sent earlier to be applied first.
