        * gnutls.c (emacs_gnutls_handshake): Made into internal function.
        (Fgnutls_boot): Start the handshake.
        (emacs_gnutls_read): Perform the handshake from the reader loop.
+       (Fgnutls_boot): Remove some debugging messages.
+       Change indentation throughout to use the Emacs style.
+       (emacs_gnutls_handshake): Cast the fds to something that's
+       possibly the expected length.
+       (emacs_gnutls_write): Return -1 if we try to write before handshake.
 
        * process.h (Lisp_Process): Add a gnutls_p field to Lisp_Process.
