port 2.1.0 - progress count leads to excessive lines in output

[BjarneDMat]

I'm running an automatic nightly update by having an update script as part of periodic daily.

The problem is, that the progress counts introduced in port 2.1.0
---> Updating database of binaries: 100.0%
---> Scanning binaries for linking errors: 100.0%
leads to an excessive amount of totally superflous lines in the log file periodic.daily.

The problem has been described in details in the groups:
