[Python-mode] display when py-shell-name tells path

[Andreas Röhler]

Hi Barry, hi all,

after fixing lp:943832, py-execute-buffer ignores full-path py-shell-name
on my machine

a running py-shell buffer now displays proudly the full path, something like

*/home/MY-NAME/SOME-DIR/OTHER-DIR/Python-3.2.2/Python*

which might not be the right thing for daily work.

OTOH it seems worth somehow to discern such a thing - think also at virtualenv.

So like the prompt-change from virtualenv maybe have some prefix-display?

Cheers,

Andreas
