[Dovecot] bug formatting results when using doveadm-server

[Angel L. Mateo]

Hello,

	I have a infrastructure using director in front of backend servers. So 
I normally run doveadm commands in director servers, not the backends. 
The problem I have is when I try to concatenate commands like this:

doveadm search -S /var/run/dovecot/auth-userdb -u ${user} SAVEDSINCE 5w 
| while read guid uid; do
    doveadm fetch -S /var/run/dovecot/auth-userdb -u ${user} 
size.physical mailbox-guid $guid uid $uid;
done

	The problem is that although when I run doveadm search command in the 
backend server I correctly get the list of mails, each line with the 
mailbox-guid and the uid of the message, when I run the same command in 
the director server, format of the list is corrupted and there are lines 
that contains just the mailbox-guid and the next the uid (of the 
previous) and the mailbox-guid of next, and so on. Like:

e62e0d3834ed094e5c7900007efb8a67 66
e62e0d3834ed094e5c7900007efb8a67 71
e62e0d3834ed094e5c7900007efb8a67 74
  e62e0d3834ed094e5c7900007efb8a67
75 e62e0d3834ed094e5c7900007efb8a67
77 e62e0d3834ed094e5c7900007efb8a67
78 e62e0d3834ed094e5c7900007efb8a67

	so I can't postprocess correctly the output. I think it could be a bug 
in the communication between the doveadm client and server.

PS: As the time of writing this email, I have realized that I could use 
fetch command directly. But, anyway, I want to report the problem/bug so 
it can be fixed.
