In _The_Unix_Programming_Environment_ (Kernighan and Pike), they say
explicitly on p. 224 that

        "/dev/tty is opened with mode 2 -- read and write -- and
         then dup'ed to form the standard input and output.  This
         is actually how the system assembles the standard input,
         output and error when you log in.  Therefore, your standard
         input is writable"
