Says who? You can make your programmers use any tools you want. Why
does a formatting tool have to be transparent? That's a policy decision
that *you* get to make.

If the server rejects any commits of badly-formatted code, then that
will "force" them to learn to write well-formatted code, or "force" them
to use a tool that cleans up their code before committing. The
pre-commit hook can help you enforce the new policy.

If any hook script modifies the data, then the working copy and
repository disagree about what files look like. Everything will break.
You *cannot* have the server change data. All you can do is have the
server reject bad data.
