Let's put this comment at the start of the file, (using `##` in keeping with most llvm-objcopy tests, to help distinguish it from lit/FileCheck directives) and elaborate on it a bit more, i.e. something like:

"Show that section names appear before symbol names in the COFF strtab. These names are only added to the strtab if they exceed 8 characters."
