Yes, of course, but then I think stderr in stdio should be reserved to 
errors coming from automate stdio itself, not from commands run within 
stdio... like "your appartment exploded, can't run stdio" sort of 
errors... =)

I quickly implemented push/pull/sync for automate in some branch, and 
automate genkey already spits out messages on clog when creating a new 
key, so this problem exists already. One possible solution for me would 
be that the P() macro would print out either to clog or cout (in stdio 
format) dependent if a command is called from within stdio or not. But I 
guess this is too complicable or not even doable without even more 
interfering magic (see how I tried to implement tickers in stdio...)
