1592  *
1593  * Win95:
1594  * - if the buffer is 0 or 1 character long then it is as if it was of
1595  *   infinite length.
1596  * - otherwise, if the buffer is too small only the section names that fit
1597  *   are returned.
1598  * - note that this means if the buffer was too small to return even just
1599  *   the first section name then a single '\0' will be returned.
1600  * - the return value is the number of characters written in the buffer,
1601  *   except if the buffer was too small in which case len-2 is returned
1602  *
1603  * Win2000:
1604  * - if the buffer is 0, 1 or 2 characters long then it is filled with
1605  *   '\0' and the return value is 0
1606  * - otherwise if the buffer is too small then the first section name that
1607  *   does not fit is truncated so that the string list can be terminated
1608  *   correctly (double '\0')
1609  * - the return value is the number of characters written in the buffer
1610  *   except for the trailing '\0'. If the buffer is too small, then the
1611  *   return value is len-2
1612  * - Win2000 has a bug that triggers when the section names and the
1613  *   trailing '\0' fit exactly in the buffer. In that case the trailing
1614  *   '\0' is missing.
1615  *
1616  * Wine implements the observed Win2000 behavior (except for the bug).
1617  *
1618  * Note that when the buffer is big enough then the return value may be any
1619  * value between 1 and len-1 (or len in Win95), including len-2.
