But instead of changing table headers to write to stdout, I think a better fix would be to make tab formatter write headers to stderr. Including headers in stdout makes it more difficult to write scripts that access the actual data. For example now you can do "doveadm who -1 | sort" and the output will work. If headers were written to stdout you'd have to make it more complicated. Also you can now easily specify what you want to do with the headers, 2>/dev/null if you don't care about them or 2>&1 if you want to include them in stdout (which works even after |sort).

I've been using "-f flow fetch text | sed s/^text=//" when training 
spamassasin. Couldn't find a straightforward 'fetch raw message'. Seems 
unnecessarily awkward. Moving headers to stderr would help this, though.
