It is, but only in a limit number of scenarios.  I completely forgot
about recalculating when deleteing ACEs, in fact.  I checked this
against setfacl on Linux again, appied a patch and uploaded a new test
release 2.4.0-0.15.  The mask recalculation behaviour should now be
as close as possible to Linux, I hope.  I also renamed the --substitute
option to --set, as with Linux setfacl.

Please give it a try.  Just, if it's still wrong, I guess a patch has
to wait until after the holidays.


Thanks a lot for testing this so extensively,
Corinna
