dovecot - Feb 2016 - [Feature Request] doveadm option to return number of messages acted upon

So I have a script for handling my specific archive and expunge needs, but it?d
be nice to be able to track how many messages are being affected.

Currently I?m doing it by firing the same search queries into doveadm search and
counting the lines of the result with wc -l, but that?s not a very pretty
solution. While I?m mostly doing it out of interest on a personal server, I
can?t imagine it?s a very scalable way to do it if you wanted to gather some
kind of metrics for example.

What I think would make sense would be for relevant doveadm commands such as
move, expunge (probably purge too) and others I haven?t thought of to have a new
option that, if enabled, will cause the command to output the number of messages
affected as the final line of output (most of these commands don?t have any
output anyway). A doveadm count command could also be a convenient, more
efficient, alternative to doveadm search | wc -l.

statistics are always nice
