[bug#48320] [PATCH v2] lint: Verify if #:tests? is respected in the 'check' phase.

[Mathieu Othacehe]

Hello Maxime,

Thanks for the new revision.

You can write longer sentences here, up to 78 columns.  If you are using
Emacs, fill-paragraph does the right thing.

It would make more sense to define "sexp-uses-tests??" later as it uses
"sexp-contains-atom" that is defined afterwards.

I think it should be "append" instead of "or". Otherwise, it fails to
detect package which 'replace is not the first phase, see mkvtoolnix for
instance.

Otherwise looks fine :)

Thanks,
