* `&' and `&&' are both logical and.  There is no binary and.
* `!' has a much higher precedence.
* The equal and relation operators have the same precedence.
* `**' is implemented, and `^' is for exponentation (not xor).
* Unary `+' in implemented.

I've coded exponentiation to return what appears to be the same results
that other versions of m4 return.
