[MPICH] MPI_Pack manual page.

[Ashley Pittman]

In investigating a application problem with the use of MPI_Pack I've
spotted what I think is a error in the MPI_Pack man page, *position is
modified by the call so position should be listed as a output parameter?

This page seems to be correct however:
