Here are a couple of additions to the StrBuilderTest class that demonstrate this problem:
> StrBuilder.deleteAll() - added to testDeleteAll_String():
>         sb = new StrBuilder("\n%BLAH%\nDo more stuff\neven more stuff\n%BLAH%\n");
>         sb.deleteAll("\n%BLAH%");
>         assertEquals("\nDo more stuff\neven more stuff\n", sb.toString());
