Update: Nothing really to see here. Please move along.

Is this meant to be run from the command line in a console window, or over a web page? If it's the console, why not just prompt the user for input by showing the default value that will be accepted with a CR ? Is it that there may be a really long path to type in, and you want to save the user some keystrokes? I suppose I don't understand the need to provide an editable prompt, even though it does sound kind of cool.
