Samuel Thibault 44bb61c8d9 Fix curses interaction with keymaps
The combination of keymap support (-k option) and curses is currently
very broken.  The patch below fixes it by first extending keymap support
to interpret the shift, ctrl, altgr and addupper keywords in keymaps,
and to fix curses into properly using keymaps.
