 * - note that this means if the buffer was to small to return even just 
 *   the first section name then a single '\0' will be returned.
 * - the return value is the number of characters written in the buffer, 
 *   except if the buffer was too smal in which case len-2 is returned
 *
 * Win2000:
 * - if the buffer is 0, 1 or 2 characters long then it is filled with 
 *   '\0' and the return value is 0
 * - otherwise if the buffer is too small then the first section name that 
 *   does not fit is truncated so that the string list can be terminated 
 *   correctly (double '\0')
 * - the return value is the number of characters written in the buffer 
 *   except for the trailing '\0'. If the buffer is too small, then the 
 *   return value is len-2
 * - Win2000 has a bug that triggers when the section names and the 
 *   trailing '\0' fit exactly in the buffer. In that case the trailing 
 *   '\0' is missing.
 *
 * Wine implements the observed Win2000 behavior (except for the bug).
 *
 * Note that when the buffer is big enough then the return value may be any 
 * value between 1 and len-1 (or len in Win95), including len-2.
