Guix documentation says that `guix upgrade` is an alias for `guix package -u`, but the latter can upgrade a list of packages, while the former fails.
## Steps to reproduce
1. guix pull
2. guix upgrade --dry-run
3. Pick two packages from the list shown in (2), say, packages A and B
4. guix upgrade A B
## Expected result
Packages A and B are upgraded.
## Unexpected result
Step 4 fails with the following message:
guix upgrade: error: B: extraneous argument
## System information
Using guix 0ae0efd with the Guix System.
