hi, miller, cyrille

the first part works as expected.

unfortunately (at least here on windows 7) the redirection of stderr 
always produces an empty file.
i tried (i think) all possible combinations that should do this, i.e.:

pd -noprefs -stderr -listdev -nogui -send "pd quit" 2> 
C:\Temp\pd_listdev.txt
pd -noprefs -stderr -listdev -nogui -send "pd quit" 
 >C:\Temp\pd_listdev.txt 2>&1

result:
the console is empty, pd quits, and "C:\Temp\pd_listdev.txt" is created, 
but empty

what also seems strange to me, is that no matter if i add the -stderr 
flag or not, the devices are listed in the console, so:

pd -noprefs -stderr -listdev -nogui -send "pd quit"
pd -noprefs -listdev -nogui -send "pd quit"

both give the same results
