push: hide description about "-f" in the hint to prevent from using it easily

"use push -f to force" in the hint at abortion of "hg push" may cause
novice users to execute "push -f" easily without understanding about
problems of multiple branch heads in the repository.

This patch hides description about "-f" in the hint, and leads into
seeing "hg help push" for details about pushing new heads.
