[arch-general] pacman's default download manager?

On my personal machine I've long-since changed XferCommand, but on doing a new install on another machine with the latest iso (behind a proxy, which is a first for me), I figured out that a problem I was having was linked to pacman NOT using wget by default. Is it just me, or wasn't wget the default before? Just to be clear, I was getting proxy related errors even after changing /etc/wgetrc (as instructed in the beginner's guide). Does pacman use curl by default now (or something else)? Once I get confirmation, the Beginner's Guide section on proxies needs a bit of changing =).
