I played with this some, and found that:
copy /b src1+src2 target         only src2 treated binary - as above
copy /b src1+src2 target /b      both files treated as binary
copy    src1+src2 target /b      both files treated as ascii
copy    src1 src2 target         appends as if +, src2 treated as binary

The actual specification for "copy" is so confusing (IMHO) that it's difficult
to see which lines are in error
