Return only user-specified Inno Setup command line switches

The support function GetCmdTail returns all command line parameters passed to Setup or Uninstall as a single string. This produces:

/SL5="$A808E8,550741730,269824,D:\Setup.exe" /DEBUGWND=$6A0ACA /verysilent /suppressmsgboxes /closeapplications /restartapplications /norestart

Is there another function or simple way of just returning the user specified command line switches:

/verysilent /suppressmsgboxes /closeapplications /restartapplications /norestart

in this particular case, whilst excluding the /DEBUGWND entry and/or any other parameters that have not been user specified?

Since Inno Setup 6.2, ParamCount and ParamStr exclude some of these internal parameters, so the if condition in the below code is not needed.

Based on a similar code I use to run an elevated installer:

function GetUserCmdTail: string;
var
  I: Integer;
  S: string;
begin
  for I := 1 to ParamCount do
  begin
    S := ParamStr(I);
    // Filter all internal Inno Setup switches
    if (CompareText(Copy(S, 1, 5), '/SL5=') <> 0) and
       (CompareText(Copy(S, 1, 10), '/DEBUGWND=') <> 0) and
       (CompareText(Copy(S, 1, 10), '/SPAWNWND=') <> 0) and
       (CompareText(Copy(S, 1, 11), '/NOTIFYWND=') <> 0) and
       (CompareText(S, '/DETACHEDMSG') <> 0) and
       (CompareText(S, '/DebugSpawnServer') <> 0) then
    begin
      Result := Result + AddQuotes(S) + ' ';
    end;
  end;
end;
