Right, I see, the ambiguous numbering with local commits may be a weak
point. But then, if you don't find the hash in the OpenWRT git, you also
know that it's not a clean copy of trunk and that's also valuable
information. People should report bugs from clean trunk, not containing
random, unknown, additional commits.
