Mel,
According to the man page, using a+X (note the capitalization) should
only set the executable bit on directories, or on files which have any
executable bit set. A quick test confirms this behavior. I think
that the combination of the two commands that Zbigniew Komarnicki
listed will result in the desired permissions for the subtree.
