Proposed resolution:

This wording is relative to N4988.

1. Modify [rand.eng.philox] as indicated:

   -1- A `philox_engine` random number engine produces unsigned integer random numbers in the closed interval [0, m]), where m = 2^w − 1 and the template parameter w defines the range of the produced numbers.

There is a typo in `philox_engine` wording that makes "-1" two times instead of one for `max()` method. The reason for that typo is that the wording was originally inspired by `mersenne_twister_engine` but after getting feedback that what is written in the `philox_engine` synopsis is not C++ code, the authors introduced the m variable (as in `subtract_with_carry_engine`) but forgot to remove "-1" in the m definition.

Note: after the proposed resolution below is applied the m variable could be reused in other places: basically in all places where the `mod 2^w` pattern appears (like `subtract_with_carry_engine` does). The authors don’t think it’s worth changing the rest of the wording to reuse the m variable. If somebody thinks otherwise, please provide such feedback.
