Browse source 
This fixes compiler warnings for implicit-ints:
warning: return type defaults to 'int' [-Wimplicit-int]
 1854:     sh_tcgetattr(int fd, struct termios *tty)
 1863:     sh_tcsetattr(int fd, int cmd, struct termios *tty)

cmd/ksh93/edit/edit.c:
- Set the return type explicitly to int and align with the prototype
  declared in include/terminal.h.
