I think we do need these.

I have been trying a patch to style gdb's meta-data output, stuff like
<unavailable>.  There are cases where the <...> contains some other
value, like:

	  fprintf_filtered (stream, " <repeats %u times>", reps);

Here we want to rewrite as:

	  fprintf_filtered (stream, " %pS<repeats %u times>%pN",
                            metadata_style.style ().ptr (), reps, nullptr);
