It’s not an interactive command, more of an helper function.
FILE-NAME isn’t provided by the user; it’s provided by the internal callsite. 
Maybe embedding the logic instead of making a separate function (which the 
original patch did) might be better?

If the user provided directory (which has no relationship with FILE-NAME and is 
read by the `read-file-name' call inside the function) is a directory, the 
basename becomes FILE-NAME. The function assumes FILE-NAME provided by the 
callsite is not a directory.
