Thanks.  That looks pretty good, but needs some tweaking:

In each place that you ExpandListArgument to get the emulator
command and arguments and write them out before an executable
name, you need to be sure to make the proper call to escape
each argument.  In each case the code just below your hunk
does this for the test arguments.

The Tests/RunCMake/pseudo_emulator.cxx tool must be able to
compile with any of the compilers we test, not just those that
host the build of CMake.  It will be more portable to use a
.c file with <stdio.h> and printf.  Also, please make it print
out each argument in quotes so one could match expected output
in the future.

Why is this needed in InitialCache.cmake?

Thanks,
