------------------------------+---------------------------------------------
 I've modified the python25 Portfile to add a readline variant which
 enables command history and tab completion for the python shell.

 It would probably be a good idea to set this variant as default unless you
 have a reason not to do so (I don't know why readline was disabled until
 now), but that's not part of this patch.

 PS: Such a patch would probably also be applicable to all the other python
 variants.
 PPS: This is my first patch to a Portfile so far, please tell me if I have
 done any mistakes.

 Cheers,

 Tom.
