        * fhandler_console.cc (fhandler_console::dup): Duplicate `insert_mode'.
        (fhandler_console::fhandler_console): Initialize `insert_mode'.
        fhandler_console::char_command): Add terminal capabilities
        "enter insert mode" = \E[4h and "exit insert mode" = \E[4l.
        Care for insert mode on terminal capability "repeat char" = \E[x;yb.
        (fhandler_console::write_normal): Care for insert mode before writing
