commit 9cfef167dc0b2bfa881c5d9eca38227fbdfd507c
Author: Ryan Scott <ryan.gl.scott at gmail.com>

    Add Read1/Read2 methods defined in terms of ReadPrec
    
    This adds new methods `liftReadList(2)` and `liftReadListPrec(2)` to the
    `Read1`/`Read2` classes which are defined in terms of `ReadPrec` instead
    of `ReadS`. This also adds related combinators and changes existing
    `Read1` and `Read2` instances to be defined in terms of the new methods.
