BUG: in io:fread/3: doesn't return eof

[Raimo Niskanen]

Erlang (BEAM) emulator version 5.3 [hipe] [threads:0]

Eshell V5.3  (abort with ^G)
1> io:fread('adhoc> ', "~d~f~f~d~f").
adhoc> 1 2.0 3.0 4 5.0
{ok,[1,2.00000,3.00000,4,5.00000]}
2>

Works fine. Please give more info about from where you read input and 
how you expect the end of file in the input to appear.
