  01 Aug 04 SHL Rework lstrip/rstrip usage
  25 May 05 SHL Rework for ULONGLONG
  06 Jun 05 SHL Drop unused code
  06 Jul 06 SHL Support compare content (IDM_SELECTSAMECONTENT)
  13 Jul 06 SHL Use Runtime_Error
  29 Jul 06 SHL Use xfgets_bstripcr
  15 Aug 06 SHL Rework SetMask args and logic
  06 Apr 07 GKY Work around PM DragInfo and DrgFreeDISH limits
  19 Apr 07 SHL Sync with NumItemsToUnhilite mods
  12 May 07 SHL Use dcd->ulItemsToUnHilite
  14 Jun 07 SHL SelectAll: make odd expression go away
  02 Aug 07 SHL Sync with CNRITEM mods
  04 Aug 07 SHL Use Runtime_Error
  05 Aug 07 SHL Rework SpecialSelect to use CNRITEM_EXISTS and
               not use pszFileName since CNRITEM_EXISTS set implies
               pszFileName not null
  14 Aug 07 SHL Revert ExpandAll DosSleep to 0
  20 Aug 07 GKY Move #pragma alloc_text to end for OpenWatcom compat
  26 Aug 07 GKY DosSleep(1) in loops changed to (0)
