I would expect we need the same check and the same message in the rename box in
the File Browser. Is there a difference?

You are right, there is an equal string. However, one can use only
GALLERY-starting strings in prompts. Or refactor some amount of code, which is
hardly worth it.

+        Sorry, you can't begin a file name with a dot. Please choose another name.

         A file named "$1" already exists. Do you want to replace it?
