unary + and C standardization

[mrm at datagen.UUCP]

The reason I heard that Ritchie objected to unary + is that it doesn't give
the programmer any power (except to insure an lvalue is an rvalue).  The
argument for adding unary + was that other languages have it, and it
makes writing a program which translates other languages into C easier.
