Because it's a different problem. The mailutils flag is there because of
security concerns with the bundled movemail. There is no file collision
in that case, because Emacs doesn't install its movemail program in
/usr/bin but in /usr/libexec/emacs/.

Right. The test doesn't add much value (if any).

Way too complicated IMHO.
