The offending output lines were commented out by Nick Coghlan in
commit 67790 with the comment "Don't print here by default, since doing
so breaks some of the buildbots".  The actual code change disables the
output rather than changing the default, so perhaps it is not quite what
Nick intended.  However, either way the intent seems to be to not
generate this output normally, which would mean that this bug could be
considered fixed in the trunk.
