Description of problem:
a user discovered a translation bug in DNF. A space is missing. This is coming from an upstream bug as a string is split in two parts:

(try to add '%s' to command line to replace conflicting packages
#287; Refs: ../dnf/cli/main.py:127

or '%s' to skip uninstallable packages) and 
#288; Refs: ../dnf/cli/main.py:130


Can you please fix this?

Here is the translated result: "(essayez d’ajouter « --allowerasing » à la ligne de commande pour remplacer les paquets en conflitou « --skip-broken » pour ignorer les paquets non installables)"

"confitou" should be "conflit ou". But this only works for french, other languages will require more than a space.

I do not now how to produce this bug, but the user uses Fedora 28.
