* mate_desktop_prepend_terminal_to_vector:
* @argc: a pointer to the vector size
* @argv: a pointer to the vector
*
* Description: Prepends a terminal (either the one configured as default in
* the user's MATE setup, or one of the common xterm emulators) to the passed
* in vector, modifying it in the process. The vector should be allocated with
* #g_malloc, as this will #g_free the original vector. Also all elements must
* have been allocated separately. That is the standard glib/MATE way of
* doing vectors however. If the integer that @argc points to is negative, the
* size will first be computed. Also note that passing in pointers to a vector
* that is empty, will just create a new vector for you.
