Subject: [PATCH] A little cleanup of cmd.c: - Remove bIsBatch variable, and
 just check for bc != NULL instead. - Since Batch doesn't return until the
 batch file is finished, CMD /C no longer needs to call ProcessInput. - Don't
 bother loading ntdll.dll on Windows 98; it doesn't export the functions we
 want to use from it.
