ah...  I can replicate.  This is weird. Perhaps some sort of pipe is 
still capturing the output?

1. update ABS
2. cp /var/abs/community-testing/pacman-contrib/* .
3. adjust dependencies to be  depends=('pacman>4')
4. makepkg -s, type in your password.  It will reinstall pacman from the 
repos and then bail because on missing deps
5. notice file named "4" in you directory containing pacman output...
