wxWidgets/src/gtk/dataview.cpp
Vadim Zeitlin 235e8ebd1a Factor out wxDataViewRendererBase::NotifyEditingStarted() 
Reuse the same code from the generic and native GTK and OS X implementations
of wxDataViewCtrl instead of triplicating it.

This fixes a small discrepancy between the wxOSX version, which didn't see the
model pointer correctly in the generated event, and all the others, but mainly
paves way for future improvements.
