Revert "Remove trailing whitespace" for white-space tests

[hakatashi]

I believe the recent "Remove trailing whitespace" commit broke tests for that white space.

Automatic validation checks of commit 7b73103 passed.

Thanks for catching this, and apologies for the mixup.

IMO it'd be better to use character references instead of (invisible, trailing) whitespace characters in these tests. It'd make them much easier to read, I think. @hakatashi @r12a?

[r12a]

@gsnedders that seemed like a sensible suggestion, so i took some time to update the files and created a PR #982

@Ms2ger please don't change tests that i submit without checking with me first, since i use the tests in other places, beside this repository, and need to keep the files the same in all locations.

[r12a]

btw, @hakatashi many thanks for spotting this!

[hakatashi]

Not at all 😃 I'm here because I'm currently implementing a module to simulate this draft spec and just quoting the test.

[Ms2ger]

@r12a if you don't want tests to be changed, please remove them from this repository.

[r12a]

@Ms2ger i didn't say that i didn't want tests to change. I asked that you notify me beforehand so that (1) we can avoid wasting time putting things back when necessary, and (2) so that i can update the tests in other places where i use them where a change is needed.
