Begins editing on a cell_editable.
The #GtkCellRenderer for the cell creates and returns a #GtkCellEditable from gtk.cell_renderer.CellRenderer.startEditing, configured for the #GtkCellRenderer type.
gtk.cell_editable.CellEditable.startEditing can then set up cell_editable suitably for editing a cell, e.g. making the Esc key emit #GtkCellEditable::editing-done.
Note that the cell_editable is created on-demand for the current edit; its lifetime is temporary and does not persist across other edits and/or cells.
