45) The "access()" system call checks access permissions on the real
id's of the process regardless of the effective ones. Doesn't return
stats, just does an internal "access()" to set u.u_error.

- remove all trailing whitespace

- fix remaining .Nm usage as well

Ok, so there could be a cost/benefit debate with this commit, but since I have
the patch we might as well commit it...
