I agree with others here that version control software should NOT be
responsible for such tasks. I've always seen pretty-printing done as part
of the build. Your cycle should go something like this (simplified):

1. Checkout
2. Edit
3. Build (with automatic pretty-printing)
4. If build succeeds, then test
5. If test succeeds, then commit
6. Cycle back to #2 for each feature to add/change

Your tests (whatever they comprise) give you confidence that your changes,
even after pretty-printing, work as you expect.

There are many tools that can do the pretty-printing, as I'm sure you
already know. You should be able to run them against your code in your
build script, be it make or something else. Since everyone MUST run the
build script to verify that changes are worthy of committing,
pretty-printing happens automatically. If you still have problems with code
not conforming to your organization's coding standards, you have a personnel
problem, not a technical one.

Good luck,
