  I've committed a fix.

  Well... that really won't work.  The regular expressions in the
"users" file are just the strings:

	Foo =~ "a*b"

  NOT
	Foo =~ "/a*b/i"

  If you want policies that are slightly complicated, use "unlang".
Really.  Delete these entries from the "hints" file, and replace them
with unlang-style policies.
