How about an option to disbale headers? (was Re: Patch for "doveadm -f table" nit)

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). > > doveadm .... 2> /dev/null > will suppress headers _and_ error messagesHm. Yeah, that's not good.>>> So, I'll add in my v2.3 TODO that tab formatter should write to stderr.. >> >> 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. >> > > How about a formatter option to enable/disable headers at all?

Added -h parameter now to hg. I didn't change the stdout/stderr behavior for now - have to wait until v2.3 for that. I guess that could also be changed to stdout then.

With -f table this behaves as expected, however with -t tab the output seems to include the separating tabs of the header line prepended to the first line of output. In other words, the header line is printed partially - only the tabs, no actual headers and no newline.
