Thou shalt not modify the transaction in the pre-commit hook. :) But
you can, if you insist, have the hook commit a second revision
immediately following the first to add that trailing newline if
necessary. Your hook script might then have to maintain a working
copy of its own in which to make such modifications. It might become
a nontrivial script. Personally I'd just leave your pre-commit hook
as-is, and get your developers to add the newline. My editor has a
setting for doing this automatically when saving any file; hopefully
the one your developers are using does too.
