This is a fallback mode after credential helpers have failed to fill
and return.  Unless these helpers pay attention to the "interactive"
configuration, they may still get stuck.  So it would be #leftoverbits
to update each credential helpers to do the right thing.

The sample credential-store backend does not have to be updated I
guess ;-)
