This is incorrect.  `system' only calls COMMAND.COM when its argument 
turns out to be an invocation of a batch file, or of an internal command 
(like `set' or `time').  In all other cases, it does the job by itself, 
eventually calling `spawnve'.  COMMAND.COM is too dumb to let it do this 
job.  For details, see the docs of `system' in the libc reference.
