[CMake] foreach() bug?

[Alexandre.Feblot at thomsonreuters.com]

Bill,

it seems this policy doesn't affect foreach():

macro(test pol)
    cmake_policy(SET CMP0007 ${pol})
    set(list)
    list(APPEND list A B "" C D)
    list(LENGTH list len)
    message("List: ${list} (length=${len})")
    foreach(arg ${list})
        message("List elem: ${arg}")
    endforeach()
endmacro()
test(OLD)
test(NEW)

returns:

List: A;B;;C;D (length=4)
List elem: A
List elem: B
List elem: C
List elem: D
List: A;B;;C;D (length=5)
List elem: A
List elem: B
List elem: C
List elem: D
