Also of note: pacman 3.1 doesn't appear to overwrite the /etc/profile file, even if you don't change it, because the package changed hands (profile != profile.bash).
When I enabled testing, fetched pacman 3.1, and then updated, I got a profile.pacnew. Moving that over to replace the existing file and logout-login fixed all the man pages that I had chance to look at. pacman, git, and a few others.
