I say

squeeze -n testing testing.zip

expecting squeeze to produce a zip archive named testing.zip from the filepath testing. 

Instead squeeze displays a dialog asking if I want to create a gzip archive named testing? Why? I just told it exactly what I wanted, no need for any dialogs, unless it's a progress dialog of course.

Oh, by the way, this dialog has two buttons a "Cancel" button and a "New" button, the "New" button just seems wrong, wouldn't "Create" be a better choice?
