     RelativeFilePaths - [bool]
         Always resolve file paths using Resolve-Path -Relative.
         The default is to use some heuristics to guess if relative or absolute is better.

   To customize your own custom options, pass a hashtable to CompleteInput, e.g.
         return [System.Management.Automation.CommandCompletion]::CompleteInput($inputScript, $cursorColumn,
             @{ RelativeFilePaths=$false }
