# POSIX says:
# - Each component that contains a pattern character shall require read
#   permission in the directory containing that component.
# - Any component, except the last, that does not contain a pattern character
#   shall require search permission.
# The second statement is not actually correct. If the last component contains
# a pattern character, only read permission is required for its parent
# directory. The expansion of foo/no_search_dir/f*e succeeds in many shells
# despite the POSIX requirements, hence the comment.
