Maybe something like:

  * guix/scripts/lint.scm (check-foo, check-bar): Move to…
  * guix/lint.scm: … here.

and also mention things that go beyond simply moving things around (if
applicable).

But again, don’t spend a whole day on this, it’s mostly so the future us
have an easily searchable log.

Ah yes, indeed.  

In that case it’s OK because (guix ui) is used as part of the linter’s
job.  Perhaps for clarity we should write:

  #:use-module ((guix ui) #:select (texi->plain-text fill-paragraph))

Uses of the ‘warning’ procedure or similar UI functionality should be
left to (guix scripts lint), though.

Thanks,
Ludo’.
