Fix some unwanted uses of Debug formatting on user-facing messages

Browse source 
While formatting for user diagnostics used `Display` for all most cases,
some small amount of cases used `Debug` instead.  Until now, `Display`
and `Debug` yielded the same output for many types. However, with path
trimming, we want to show a shorter path for the user, these cases need
fixing.
