parser error on :info command

[Duncan Coutts]

hugs gets confused by the following command

:info .
Unknown module `'
Unknown reference `'

Other operators work fine:

:info +
infixl 6 +
(+) :: Num a => a -> a -> a  -- class member

It looks like the parser is confusing the (.) operator with the dot in 
'Module.value'

If this is difficult, maybe the info command could accept bracketed operators 
like the :type command.

:type (.)
(.) :: (a -> b) -> (c -> a) -> c -> b
