I'm not entirely sure whether "Dot-Verzeichnis" will be understood, but
the more German "Punkt-Verzeichnis" is even stranger and I actually
never heard anybody using it. Another, more cumbersome, candidate is
"Programmkonfigurationsverzeichnis im Heimatverzeichnis des Benutzers".
Eventually, it's way easier to just print the actual directory path
instead.

The second overwrite message without any further conflicts is quite
weird: If there are no further conflicts, the "yes to all" and "no to
all" choices don't make any sense. However, in order to get rid of them,
the source code has to be changed to allow for a more user-friendly
interface, which considers a case where the initial conflict prompt
refers to a single case.
