My use case is very simple. Give an argument to a program that expects a 
single filename/path.

If you give it an unquoted and unescaped filename it will break parsing 
the args thinking there are many.

When invoking from bash with auto completion the filename will get 
escaped as required. When cutting and pasting into a debugger prompt for 
args, not so.

The easy workaround for me is a few lines of python that emits a quoted 
filepath.
