Another thing I forgot to mention (but did wonder).  The new helper
function does allow LookupAccountSidA() to fail.  Should it fall
back to ConvertSidToStringSidA() that the original has been using?

In any case, I do not think a failure to convert will result in an
attempt to format ("%s", NULL) thanks to the existing code that uses
the stringified SID, which is good.
