When the destination argument D of one of these functions is an existing directory and the intent is to act on an entry in that directory, D should now be a directory name. For example, (rename-file "e" "f/") renames to 'f/e'. Although this formerly happened sometimes even when D was not a directory name, as in (rename-file "e" "f") where 'f' happened to be a directory, the old behavior often contradicted the documentation and had inherent races that led to security holes. A call like (rename-file C D) that used the old, undocumented behavior can be written as (rename-file C (file-name-as-directory D)), a formulation portable to both older and newer versions of Emacs. Affected functions include 'add-name-to-file', 'copy-directory', 'copy-file', 'format-write-file', 'gnus-copy-file', 'make-symbolic-link', 'rename-file', 'thumbs-rename-images', and 'write-file'.
