No need: =E2=80=98-u=E2=80=99 takes an optional regexp.  When you type =E2=
=80=9C-u --fallback=E2=80=9D,
it takes =E2=80=9C--fallback=E2=80=9D as that regexp.

This is a common mistake though, so we could change =E2=80=98guix package=
=E2=80=99 to at
least emit a warning then the regexp starts with a hyphen.

Thoughts?

Ludo=E2=80=99.
