Makes sure files end in a newline and only a newline.

You cant just create a PR with 433 changed files and not provide a description of what you did and why - please do that, and for all future PRs please

Hello @gmcdonald if you have been following the last 3+ months or so of development of Apache OpenOffice you will in fact see that many PRs have been merged with this same format.

• 655 files: pre-commit(trailing-whitespace): autofix .hrc files #350
• 376 files: pre-commit(end-of-file-fixer): autofix more cxx files in main #321
• 225 files: pre-commit(end-of-file-fixer): autofix more cxx files in main #317
• 110 files: pre-commit(trailing-whitespace): autofix .pm files #346
• and many more

@Pilot-Pirx and I have been working together to develop a pre-commit framework and the description of what has been changed really is in the commit message.

These are official pre-commit hooks and they are used on many ASF projects.

https://github.com/pre-commit/pre-commit-hooks

When the hooks were first added there was a lot more information and descriptions about them.

For example #261

Is there really any need to write up more ?

[gmcdonald]

All PRs should have descriptions, that what the field is there for.

Yes I have been following along, as a PMC member I do take an interest.

From time to time GitHub and GitBox do not synchronize...
Like just now. Then I have to do another small change to get it in sync.
