changes to terminal_init(). (DLR)
- Remove redundant include of limits.h from nano.c. nano.c
includes nano.h and nano.h includes limits.h. (DLR)
- Add a func_key flag to the low-level input functions and the
currently existing high-level input functions, to indicate
extended keypad values. This is needed for UTF-8 support.
Changes to get_kbinput(), get_translated_kbinput(),
get_shortcut(), get_edit_input(), etc. (DLR)
