[Boost-build] common.copy target location

I am using Boost 1.67.0, and I just recently discovered a change in its 
behavior compared to previous versions.  I am running unit tests, and 
these tests require a copy of a configuration file in the same directory 
as the running executable.  To make that work, I added an explicit 
dependency to the unit-test target and an explicit target performs the 
copy, like so:

        unit-test ParliamentTest
                :	[ glob $(SourceDir)/*.cpp ]
                        list-of-libraries
                :	<target-os>windows:<dependency>ParliamentConfig.txt
                :	# default build
                :	# usage requirements
                ;

        explicit ParliamentConfig.txt ;
        make ParliamentConfig.txt : $(SourceDir)/ParliamentConfig.txt : 
@common.copy ;

In prior versions of Boost.Build, the copy would land in the same 
directory as the test executable, e.g., 
"<output-dir>/msvc-14.1/release/address-model-64/threading-multi/ParliamentConfig.txt", 
but in Boost 1.67.0 the copy lands in "<output-dir>".

Is this change expected?  How can I get back to the old behavior?

Thanks,

Ian
