If you don't mind additional word-smithing I would say this
differently still.  I don't generally like negative logic such as
non-this or not-that and would prefer positive set groups.

  Traditional and POSIX systems return EPERM but Linux intentionally
  returns EISDIR to improve upon the situation.
