Knot 2.3.2: zone name not fully-qualified in log

Knot 2.3.2 is logging the zone name inconsistently in the log file. For example, here the output of "knotc zone-status":

[.] type: slave | serial: 2016111001 | next-event: refresh in 0h24m11s | auto-dnssec: disabled | transaction: none
[arpa.] type: slave | serial: 2016111101 | next-event: refresh in 0h17m56s | auto-dnssec: disabled | transaction: none
[root-servers.net.] type: slave | serial: 2016102000 | next-event: refresh in 0h31m57s | auto-dnssec: disabled | transaction: none

Note how all the zones are fully qualified.

But now note how the zones show up in the log:

2016-11-11T09:47:24 info: [arpa] refresh, outgoing, 2001:67c:2e8:11::c100:13be@53: zone is up-to-date
2016-11-11T09:55:19 info: [.] refresh, outgoing, 2001:67c:2e8:11::c100:13be@53: zone is up-to-date
2016-11-11T10:03:05 info: [root-servers.net] refresh, outgoing, 2001:67c:2e8:11::c100:13be@53: zone is up-to-date

So the root zone shows up as a lone dot, but "arpa" and "root-servers.net" are missing their dots. I think that the zone names in the log should be consistent, ie. they should all be fully qualified.
