When updating MediaWiki with CheckUser also installed, the fixTrailingSpacesInLogs.php script is run. However, if there are no rows in the cu_log table the output is confusing. The output is:
Processed 200 rows out of .
This is run on every CI run as part of the installation of MediaWiki before running tests. As such, fixing the output makes it clearer which script is printing this information in case anyone wants to inspect it.
