Hi,

Is this expected?

  [0] [email-masked]:~/my-guix
  $ guix build --with-source=. guix
  guix build: warning: transformation 'with-source' had no effect on guix-0.14.0-9.bdf0c64
  /gnu/store/kxihyd1f9kxrh5s2r2yk1f1kwbnxnbvs-guix-0.14.0-9.bdf0c64
  [0] [email-masked]:~/my-guix
  $ guix build --with-source=$(pwd) guix
  guix build: warning: transformation 'with-source' had no effect on guix-0.14.0-9.bdf0c64
  /gnu/store/kxihyd1f9kxrh5s2r2yk1f1kwbnxnbvs-guix-0.14.0-9.bdf0c64

  $ 

The manual provides the following examples (see: (guix) Package
Transformation Options), so I was a little surprised that the similar
invocations above didn't work for Guix:

  guix build ed --with-source=mirror://gnu/ed/ed-1.7.tar.gz
  guix build guile --with-source=../guile-2.0.9.219-e1bb7.tar.xz

For the record, it DOES work if I run:

  guix build --with-source=guix=$(pwd) guix
