By the very nature of elf-dump's output, I would expect anyone (even a
newbie) to look for an alternative (examples in other tests) or at
least ask on the mailing list and/or IRC. Moreover, hopefully folks
knowledgeable about this area would react on a patch that does
something that could be done better.

And, I will add, "appreciated".
