"box" type description

I believe the "box" type description is slightly incorrect:

# \dT box
                     Liste der Datentypen
   Schema   │ Name │               Beschreibung
────────────┼──────┼──────────────────────────────────────────
 pg_catalog │ box  │ geometric box '(lower left,upper right)'

While the syntax '((3,4),(1,2))'::box works, the canonical spelling is
'(3,4),(1,2)' and hence the description should be:

geometric box '(lower left),(upper right)'
