- Add in Pico's -p flag, (-p, --preserve). To preserve the XON and XOFF keys (^Q and ^S). Add warning if we invoke -p and add checks for using --preserve (to skip warning) and --pico (to force showing it). New flag PRESERVE, function do_preserve_msg(), changes to main(), signal_init()

New flag PRESERVE, function do_preserve_msg(), changes to main(),

- Search history and replace history up/down cursor arrows, w/history
tab completion, not available w/NANO_SMALL. Changes to
statusq, others (Ken Tyler). Added shortcut to search/replace
