issue with read_stream_to_codes/2 on windows

Hi Jan,

Here is an issue with read_stream_to_codes/2 on windows:

D:\>echo hello | swipl -g "read_stream_to_codes(user_input, Codes), 
atom_codes(Atom, Codes), write(Atom)"
|:
ERROR: Prolog initialisation failed:
ERROR: read_util:read_stream_to_codes/2: I/O error in read on stream 
user_input (The handle is invalid.
)

Typing a ^Z after "hello" works:

D:\>echo hello^Z | swipl -g "read_stream_to_codes(user_input, Codes), 
atom_codes(Atom, Codes), write(Atom)"
hello

but this cannot be done for other cases like:

D:\>type hello.txt | swipl -g "read_stream_to_codes(user_input, Codes), 
atom_codes(Atom, Codes), write(Atom)"
|:
ERROR: Prolog initialisation failed:
ERROR: read_util:read_stream_to_codes/2: I/O error in read on stream 
user_input (The handle is invalid.
)
