[issue1927] raw_input behavior incorrect if readline not enabled

[Martin Panter]

Martin Panter added the comment:

The way I see it, input() is mainly geared for prompting to stdout, and it is just one aspect that strangely uses stderr:

* Documentation says stdout
* Stdout is checked if it is a terminal and not redirected
* Gnu Readline is configured for stdout
* The fallback for non-terminals uses stdout

Arguments for using stderr:

* Consistency with Unix shell
* Consistency with the Python interactive interpreter prompt

Maybe it is more ideal to use stderr (I have no idea). But I think that would be a more drastic change.
