My take on this one:
tooltip_str = g_string_sized_new (512);
categories = xfce_menu_item_get_categories (item);
if (categories != NULL)
{
g_string_append (tooltip_str, _("<b>Categories:</b> "));
for (lp = categories; lp != NULL; lp = lp->next)
{
g_string_append (tooltip_str, (gchar *) lp->data);
if (lp->next != NULL)
g_string_append (tooltip_str, ", ");
}
}
command = xfce_menu_item_get_command (item);
if (command != NULL && *command != '\0')
{
if (categories != NULL)
g_string_append_c (tooltip_str, '\n');
g_string_append_printf (tooltip_str, _("<b>Command:</b> %s"), command);
}
