After this was discussed at the Hangout a few weeks back, I had been
thinking about it more.
My initial request was for warnings to be returned along with query
results. Some initial work was posted last fall to add warnings to the RPC
protocol, but unfortunately it was not brought to completion. These kinds of
warnings can be received by JDBC and ODBC sources and many tools show them to
users.

In the hangout we discussed that this changeset is currently logging when
part of a file is ignored. I don't believe that there is currently an
expectation that users should have to grep through a log file to find out any
additional information about the execution of a successful query, the log files
are there for admins to debug system issues.
I still think it would be good to have a way to remove the need to look
through the log file to see if this behavior was used in a query, but as there
wasn't a lot of concern expressed by others when we discussed it, I'm changing
my vote to a +0.
