[pyrepl-checkins] r43378 - pyrepl/trunk/pyrepl/pyrepl

Author: arigo

New Revision: 43378

Modified:
   pyrepl/trunk/pyrepl/pyrepl/commands.py
Log:
As discussed on #pypy: the up key should move into the previous
history item when pressed on the first line of the input buffer,
and symmetrically for the down key.  This should give a feeling
of the up/down key going through all the *lines* entered so far.

(An experimental check-in, feel free to revert.)
