Hi,
I found some improvements in Client Applications in /src/bin/scripts when I
resumed development of progress monitor for cluster command.
Attached patch gives the following query a semicolon for readability.

Even if you apply "data-at-rest-encryption-wip-2018.07.25.patch" to the master
branch,
the same patch error will occur.
