the pipe template is split on spaces into an argument list

the template parameters are expanded.
In earlier kernels, the template parameters are expanded first and
the resulting string is split on spaces into an argument list.
This means that in earlier kernels executable names added by the
%e and %E template parameters could get split into multiple arguments.
.I %e
and
.I %E
template parameters could get split into multiple arguments.
So the core dump handler needs to put the executable names as the last
argument and ensure it joins all parts of the executable name using spaces.
Executable names with multiple spaces in them are not correctly represented
in earlier kernels so the core dump handler needs to use mechanisms to find
in earlier kernels,
meaning that the core dump handler needs to use mechanisms to find
the executable name.
