    	* src/persp/dbgperspective/nmv-proc-list-dialog.cc:
    	(ProcListDialog::Priv::Priv): Set the OK button as the default widget
    	for the dialog. Make pressing enter in the filter entry activate the
    	default widget of the dialog.
    	(ProcListDialog::Priv::on_filter_entry_changed): If the filtered
    	result set amounts to only one row, select that row.
    	(ProcListDialog::Priv::is_row_visible): Count the number row that is
    	going to be part of the filtered result set.
