liststore issue 2 - which 'path' comes from signal

[Mike Martin <redtux1 gmail com>]

according to the docs the path reference is

edited signal = path
editing-started = path
changed = path_string

which I thought meant that path would be a treepath (ie: an object) and
path_string would be a reference to the row (an integer in the case of a
simple liststore)

However in all three cases the value is the same ie: an integer, not an
object

Can anyone clarify this

thanks

Mike
