I just thought of another issue worth documenting:
On systems where access(,X_OK) gives bogus results when run as root, it
is also possible for 'test -x' to give those same bogus results (that
is, POSIX allows but discourages test -x as root to always succeed,
where no one can actually execute the file). Also, in the presence of
ACLs, it is unspecified whether test matches the ACLs or just the stat
mode bits (POSIX recommends matching the ACLs, but that in turn can be
surprising when a file mode 0600 owned by someone else passes 'test -r'
for the current user due to an ACL).
