Hi,

I was testing emacs-racer 1.2 with the Emacs 27.1 release candidate. Unfortunately, the tests fail with the following log:

make unit
make[1]: Entering directory '/tmp/guix-build-emacs-racer-1.2.drv-0/source'

      :form
      (equal "foo [strr`] bar

      :value nil :explanation
      (arrays-of-different-length 21 17 "foo [strr`] bar
