Looks nice!

Could you have a go at adding a test for | and maybe * and **? But if you can't get it to work then we can merge anyway and I'll do it some time later.

Hmm, I hadn't realized that erts files were only introduced in 29.1, so the tests are failing in 27.2 and 28.2 right now. If you have any other ideas about a nice way to test it, that would be great. Or I guess I could make the erts tests conditional on the Emacs version.

I guess doing the same thing manually in elisp wouldn't be too bad, so I can convert the erts files to plain elisp if you'd like the tests to continue supporting Emacs 27/28.

Oh huh, TIL about erts, that's interesting!

But actually I'm already using something else very similar: the ecukes code in the features/ directory. You can either migrate your tests to that or merge without the tests and I'll do it :)

(And yeah I'd like to retain support for older Emacs versions for now)

[AjaiKN]

Ah, somehow I totally missed the features/ directory!

I'm actually not sure if I'll have the time in the near future, so merging it without the tests would be great. Thanks! (And I've copied the erts file here in case you want to reference it when adding the tests.)

Thanks! 🙂
