Replace directory mv's with cp -r when the move potentially crosses filesystem borders.

Apparently, Msys' mv command fails to move directories across filesystem borders (like
from a directory on the c drive to a mounted samba share).
I hit this issue because my tmp dir is on a different filesystem from
my base dir.
