(1) Checking for invalid "control=" modifiers was not working (for example,

"submission" was allowed in a DATA ACL, though that is too late). Proper
checks are now done. (2) Minor fix to the testing "List" script to
ignore CVS directories.

+ 8. "control=submission" was allowed, but had no effect, in a DATA ACL. This
+    was an oversight, and furthermore, ever since the addition of extra
+    controls (e.g. 4.43/32), the checks on when to allow different forms of
+    "control" were broken. There should now be diagnostics for all cases when a
