* fhandler.cc (fhandler_base::open): Don't set binmode if already set. Don't

check for file.  Files should already be set.  Report on binary mode for
debugging.
(fhandler_base::fhandler_base): Don't set default binmode here.  That's for
later.
* fhandler_console.cc (fhandler_console::output_tcsetattr): Don't set binmode,
ever, for console.
* fhandler_disk_file.cc (fhandler_disk_file::open): Always set the binary mode
to the value derived from mount table.
* path.cc (mount_info::conv_to_win32_path): Default to binmode if path does not
translate into anything in the mount table.
