First, sorry about this, I completely slipped on writing documentation
for this.

There's a test for this style:

	gdb_test_no_output "set print repeat 3"
	gdb_test "print {0,0,0,0,0,0,0,0}" \
	    " = \\{0 [limited_style {<repeats.*8.*times>} metadata]\\}"

It's used in a number of places where gdb is attempting to display some
kind of data from the inferior but instead prints some
internally-generated text, e.g.:

  fprintf_styled (stream, metadata_style.style (), _("<unavailable>"));

I'm not completely sure of the best way to describe this.
