I mean from this line on down textually in this file.  I.e. `// for testing only` is not needed for any of the `#include` directives in this file from line 6 through the end of the includes.  I phrased it in terms of `bslmf_...` because it is hard to talk about line numbers in the middle of a diff.

The important thing is the principle: since this is a `bslalg` component, `// for testing only` is needed only for `bslalg` includes that are not already listed in the `.h` or `.cpp` file.  The includes from `bslmf` and other packages are already part of the component's dependency envelope, so they do not need to be noted.
