That's what I thought at first, too, but simply trying it out proved me wrong (again, in both MSYS1/2):

$ for d in "$(env | grep -Ei '^PROGRAM(FILES($X86$)?|W6432)=' | cut -d '=' -f 2- | sort -u)"; do echo "$d"; done C:\Program Files C:\Program Files (x86)

Note that the path, although they are containing spaces, are on separate lines.
