gnus-article-save-part's setup of appending the proposed filename to the

Forwarded to the ding list in case any changes need to be made to how
gnus prompts for output filenames....

Probably the best choice is to do like C-x C-w does:
- don't insert initially the file name in the minibuffer.
- let M-n insert the default file name in the minibuffer.
- if the user enters just a directory name, append the base file name
  to it.
