** `char-direction-table' and the associated function `char-direction'
were deleted. They were buggy and inferior to the new support of
new optional arg COPY-CONTENTS, if non-nil, makes the function copy
the contents directly into a pre-existing target directory.

This requires Emacs to have been built with GnuTLS support.
-The main functions are `open-gnutls-stream' and `gnutls-negotiate'.
-It's easiest to use these functions through `open-network-stream'

+delayed-warnings-hook after post-command-hook. At present, this is
+only used by Emacs on some platforms to display warnings during
