klutzy 7f203b6955 pprust: Add parentheses to some Expr ... Some `Expr` needs parentheses when printed. For example, without parentheses, `ExprUnary(UnNeg, ExprBinary(BiAdd, ..))` becomes `-lhs + rhs` which is wrong. Those cases don't appear in ordinary code (since parentheses are explicitly added) but they can appear in manually crafted ast by extensions.		2014-05-13 17:24:08 -07:00
