OK. I've seen in Appendix A to the Python Tutorial
(<http://www.python.org/doc/2.2.2/tut/node13.html>)
how to use control-P to access an input line higher up in the buffer. It
retypes it on the current line. But I don't understand how to edit the line
as described: after altering the line, if I press Return I get a syntax
error (the line was in the middle of a function def); if I press control-N
repeatedly until I get back to the bottom of the buffer, nothing gets
edited. Is there somewhere that describes the procedure to use and its
limitations, which perhaps I'm exceeding here?
