[Python-3000] Low-hanging fruit: change interpreter prompt?

[Giovanni Bajo]

Hello,

it's a minor issue, but I was wondering if the interpreter prompt could be 
changed in Py3K. The current prompt is ">>>" which happens to match the 
standard character used for quotes in e-mails. As a result, intepreter 
sessions might look funky when copy & pasted inside mails.

Given that showing interactive sessions in e-mails is *very* common and 
encouraged, it might be worthy to change the prompt to avoid this conflict. 
Something like "-->" or "---" or "%%%" or really *anything* else but sequences 
of ">" and "|" would do.
