One thing I’ve noticed (not just with Pkg, but in general in a lot of Julia code), is the issue of always dumping out large backtraces when getting exceptions that come from invalid user input.  
I feel that when something is dealing with user input, such as in the below example at the Pkg REPL (good work Oh REPL Jedi @kristoffer.carlsson! 😀), that all errors should be trapped (with a run-time debugging to display the backtrace if desired), and a short message understandable to a basic user (as opposed to somebody trying to track down a problem in the package manager code), such as a simple `Directory “/s/CharSetEncodings” not found".

Any hope of getting that sort of ease-of-use issue handled before v1.0?
