Correction to doc on Accessing Arrays from C

Thanks to Ludovic for the new wording!

* doc/ref/api-compound.texi (Accessing Arrays from C): Correct text to
  reflect the current implementation of scm_array_get_handle and
  scm_array_handle_release - which don't actuall do any dynwind stuff.

 You must take care to always unreserve an array after reserving it,
-also in the presence of non-local exits.  To simplify this, reserving
-and unreserving work like a dynwind context (@pxref{Dynamic Wind}): a
-call to @code{scm_array_get_handle} can be thought of as beginning a
-dynwind context and @code{scm_array_handle_release} as ending it.
-When a non-local exit happens between these two calls, the array is
-implicitely unreserved.

-That is, you need to properly pair reserving and unreserving in your
-code, but you don't need to worry about non-local exits.

-These calls and other pairs of calls that establish dynwind contexts
-need to be properly nested.  If you begin a context prior to reserving
-an array, you need to unreserve the array before ending the context.
-Likewise, when reserving two or more arrays in a certain order, you
-need to unreserve them in the opposite order.

+In addition, array reserving and unreserving must be properly

 Once you have reserved an array and have retrieved the pointer to its
 elements, you must figure out the layout of the elements in memory.
