Description
sys.stdin.read(), sys.stdin.readlines(), etc. do not handle ctrl-D at the beginning of a line as EOF (except on ports like unix). So for instance, there's no way to terminate input when doing sys.stdin.readlines().
Is this something that should mimic CPython on an OS-less port? Some lower-level stream read routine could check if the stream was sys.stdin and handle ctrl-D specially.
(tested on esp8266 port)

Research direction
Start by tracing sys.stdin.read() and sys.stdin.readlines() on the esp8266 port, then compare their lower-level stream handling with the unix port and CPython behavior. Done means ctrl-D at the beginning of a line is recognized as EOF for these input operations on the relevant OS-less port.
