configitems: do not directly match generic items
Before this changesets, a literal '.*:foo$' config would match a registered
'.*:foo$' generic. This is wrong since generic should be matched through
regular exception only. This changeset fixes this problem.
Thanks for to Yuya Nishihara for spotting the issue.
Hello, Foobar
['Hello, Fo, =;:<o', 'Hello, Bar']
