Don't do that. Instead, you can write a pre-commit hook which rejects
the commit of any file that doesn't end with that line. Then instruct
your developers to add that line themselves before committing.

That's exactly why you mustn't modify a transaction: the working copy
will think it has a file at, say, revision 42, but the repository
will think revision 42 looks different. When you later try to update,
things will blow up.

Keyword substitution works differently. It works on the client side
only. The keywords are only expanded to their actual values upon
checkout or export; they're not stored that way in the repository.
