Alternative nSelectors patch (Was: bzip2 1.0.7 released)

So the https://sourceware.org/git/bzip2-tests.git was integrated into
the buildbot and it turned RED. As expected, since without this fix it
fails with:
 - ./lbzip2/32767.bz2 bad decompress result

So I have now pushed the patch and hopefully that turns the buildbot
green: https://builder.wildebeest.org/buildbot/#/builders?tags=bzip2

Cheers,

Mark
