Well, a token can only be treated as a special keyword if it is unquoted.
As an example, in the 'database' field, the bare token 'replication'
is a keyword meaning the pseudo-database for streaming rep. Whereas
the quoted token "replication" would mean a real database which is
called 'replication'.
Likewise, the bare token 'all' in the username field is a keyword --
it matches any username. Whereas the quoted token "all" would only
match a user named 'all'.
Therefore, token_is_keyword only returns true where the token matches
the given string as is also unquoted.
Does that make sense?
