I did intentionally not mention that, as there's a lot of tools out
there, many of which doesn't have/want such a feature.

It still doesn't change that there would be a spurious commit out there
muddling the waters, particularly regarding the quite important "last
touched" date.

I'd expect such a commit to put a fair amount of strain on the
repository infrastructure, considering that it'll have over nine
thousand source files touched, with a change to possibly every line of
every file.

Not to mention that such a script cannot deduce the intended size and
purpose of tabs, so the process/output would have to be vetted by a
human to ensure that it has not screwed up indentation/alignment.
