The current code is very naive:

* A R_OK check always succeeds if the file's attributes can be read
   at all
* A W_OK check fails if the file has its DOS read-only attribute set
* A W_OK check always succeeds for a directory (because read-only means
   something else for directories).

Would you care to propose some wording for the docs? I'm quite happy
to commit if we can come to an agreement.
