This is a result of discussion on lkml on usefulness of x bit on dirs.
It adds new flag to chmod:
chmod -R a+R dir
R=(r for files, rx for dirs)
Without this flag, in order to achieve functionality of above command
one needs to write ridiculously long script.
chmod manpage is not updated (I don't know manpage syntax)
