+// This test relies on library/std/src/error.rs *not* being included in the error message, so that
+// we can test whether a file not included in the error message affects it (more specifically
+// whether the line number of the excluded file affects the indentation of the other line numbers).
+//
+// To test this we're simulating a remap of the rust src base (so that library/std/src/error.rs
+// does not point to a local file) *and* we're disabling the code to try mapping a remapped path to
+// a local file (which would defeat the purpose of the former flag).
+//
+// Note that this comment is at the bottom of the file intentionally, as we need the line number of
+// the impl to be lower than 10.
