Re: [PATCH v1] name-hash: properly fold directory names in adjust_dirname_case()

My personal favorite would be to spell out what we expect and run a diff.
When it fails, we can see what fails, and the function would look
like this:

I'd rather not to have the "sort" there; output from ls-files is
meant to be stable; passing it through sort would miss breakages.  I
agree that comparison between "expect" and "actual" is a good idea
nevertheless.

Speaking of styles, I'd prefer to reserve use of "touch" to cases
where resulting timestamp matters, and not "make sure it exists".

Thanks.
