#156 TGnuGettextInstance.ngettext broken if SearchAllDomains is set to True

[Olivier Sannier]

When SearchAllDomains was introduced the patch code suggested to change TGnuGettextInstance.ngettext like this:

  domain := curmsgdomain;
  domainIndex := -1;
  repeat
    Result := dngettext(domain, singular, plural, Number);
    Inc(domainIndex);
    if domainIndex < domainlist.Count then
      domain := domainlist[domainIndex];
  until not SearchAllDomains or ((Result <> singular) and (Result <> plural)) or (domainIndex >= domainlist.Count);

Upon inclusion, it has been rewritten to use a while loop like this:

  Result := dngettext(curmsgdomain, singular, plural, Number);
  if SearchAllDomains then begin
    domainIndex := 0;
    while (Result <> singular) and (Result <> plural) and (domainIndex < domainlist.count) do begin
      domain := domainlist[domainIndex];
      Result := dngettext(domain, singular, plural, Number);
      Inc(domainIndex);
    end;
  end;

In doing so, the condition for the loop should have been completely inverted but the tests on Result were left as is.
This results in the fact that a valid translation found by the initial call is immediately overwritten by the call to dngettext in the loop.
The loop condition should read like this:

    while ((Result = singular) or (Result = plural)) and (domainIndex < domainlist.count) do begin

Note how the tests on result have been inverted while still being grouped together.

With this, I now have the proper translation being returned.
