I didn't see that being mentionned anywhere, but I guess compared to 
running date once for every line
I could live with a strlen().  :-)
it'd probably be more efficient than doing it one char at a time.

wonder if it would want to be flushed less often if stdout was a file..
I think stdio would do the right thing in most cases so I guess teh 
fflush woudl only be needed at the end, after the last file,
or maybe just on a signal handler so it flushes out the last buffer on ^C
