2010-11-10  Werner Koch  <wk@gnupg.org>

        Port my patch for 1.5 dated 2009-10-14 to 1.7.3.

	* encfs/main.cpp (processArgs): Add option --annotate.
	(EncFS_Args, processArgs): Support annotate option.
	(main): Print status messages.
	* encfs/FileUtils.h (EncFS_Opts): Add field ANNOTATE.
	* encfs/FileUtils.cpp (userAllowMkdir): Add arg PROMPTNO.
	(createV6Config): Make use of ANNOTATE option.
	(initFS): Ditto.
	* encfs/encfsctl.cpp (cmd_export): Adjust call to userAllowMkdir.
	(do_chpasswd): Add arg ANNOTATE.
	(chpasswd, chpasswdAutomaticly): Pass false for ANNOTATE.
