balazske added a comment.

The standard streams may need special handling, this can be useful for 
`StreamChecker` too. One problem is that the standard streams can be changed by 
the program, so we can not know for sure if these are the original values. 
Still it can be better to assume that `fileno` can not fail if used with the 
standard streams.
The result with `ftell` looks interesting, I checked this case already and I 
think the note tag is missing because there is a hidden conversion so the 
original symbol (that is set to interesting) is different than the real `ftell` 
function call.
