Important Feature Request: Ask if changes should be saved when exiting from EDIT to prevent loss of changes

I am so used to simply clicking on the "X" in the upper right corner of apps like Notepad and having that app then ask if changes should be saved. I discovered the hard way today that Edit won't do this. Instead, it simply closes without saving any changes.

Please change this so that Edit will behave as almost every other known Windows app does by asking the user if they wish to save changes.

No file or test is named in the issue. Start by tracing how EDIT handles the upper-right X and exits with unsaved changes; done means closing prompts whether to save, preserves the user's choice, and does not silently discard edits.
