sfeed_curses: cast character for SFEED_AUTOCMD to unsigned char

Otherwise a character like \xa0 (160) would be negative and goto the event,
since a negative return value in readch() is used for errors or reserved for
signal handling.

Noticed while testing mouse X10 encoding with extended buttons, like button 7:

	SFEED_AUTOCMD="l$(printf '\x1b[M\xa0!!')j" ./sfeed_curses ~/.sfeed/feeds/*
