I suppose it's there for a clean implementation of operators in C.
While the unary minus returns the negative of the operand the unary
plus returns the value to avoid ambiguity, i.e. shall the unary plus
return the positive of a negative operand, as the unary minus does?
IMHO, not a result I'd expect.
