   774     "open a pipe reading from aCommand and return the complete output as a string.

   775      If the command cannot be executed, return nil.

   776      The command will be executed in smalltalk's current directory.

   777      errorDisposition may be a stream or one of #discard, #inline or #stderr (default).

   778        #discard causes stderr to be discarded (/dev/null),

   779        #inline causes it to be merged into the PipeStream and

   780        #stderr causes it to be written to smalltalk's own stderr.

   781        a stream causes stderr to be sent to that stream (internal or external)

   782        Nil is treated like #stderr"
