+       * files.c (open_file): Open files using their full paths
+       whenever possible, so that ~user/file.txt and "~user/file.txt"
+       are treated the same way if ~user is a user's home directory.
        * files.c (real_dir_from_tilde): Simplify.
+       * rcfile.c (parse_include): Open files using their full paths
+       whenever possible, so that ~user/file.txt and "~user/file.txt"
+       are treated the same way if ~user is a user's home directory.
+       * rcfile.c (parse_include): Properly check for the included
+       file's being a directory, a character file, or a block file.
+       * rcfile.c (parse_include): For consistency, display the
+       filename as the user entered it if we can't read the specified
+       file.
        * winio.c (parse_kbinput): Interpret Cancel and Shift-Cancel.
        * winio.c (get_escape_seq_kbinput): Add missing comments.
