Hi!

I installed a package with --with-git-url and --with-branch to my profile:

     guix install kakoune
--with-git-url=kakoune=https://github.com/mawww/kakoune.git
--with-branch=kakoune=breaking-cleanups

However, now I can't run `guix upgrade`. I get the following error:

     guix upgrade: error: the source of kakoune@2021.08.28 is not a Git
reference

I also tried to add the same transformation options to `guix upgrade`,
but I got the same error.


Is installing packages with the --with-git-url transformation to
profiles not supported? Or is this a bug?

Ideally I'd like `guix upgrade` to remember the way in which this
package was installed and update it accordingly. In this case by
fetching the latest changes from the breaking-cleanups branch. Is this
not how this transformation option works?

Thanks :)
