<pre>Here's a common concatenation macro, e.g. from range-v3:
#define RANGES_CXX_FEATURE_CONCAT2(y, z) RANGES_CXX_ ## y ## _ ## z
This gets formatted as:
#define RANGES_CXX_FEATURE_CONCAT2(y, z) RANGES_CXX_##y##_##z
I'm not sure there's any option to control the spacing around the ##s, but this
is not easier to read.</pre>
