Using Page*() triggers a camelcase warning, but shouldn't.

Introduced by be987d9f80354e2e919926349282facd74992f90, which added the
other Page flag users.

Pipe ('|') at the end of a grouping doesn't cause the grouping to match
an emtpy string, use ? after the grouping instead to get the desired
behavior.
