Subject:         * fhandler.h (class fhandler_console): Add members
 `insert_mode'.         * 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         to the console.         (array keytable): Add
 keymapping for modified cursor and control         block keys (xterm like).
