Fixes #31 
So you propose that in order to do the default resume, you would need to specify .lastIndex as well if you wanted it to work like the default?  If so,I think thats perfectly fine though I think I would like to have a check there if there isn't / (meaning no full path), that it handles just a filename and puts it in the default location with whatever name you give it.  Thoughts?
