This was fixed by #114, but an outstanding question remains. Why did we have to hard code the edge case checking, instead of it getting caught by the inclusion checking logic?

Coming back to this, I reverted 7b15e23 and tried to recreate this issue but couldn't. I get the expected result:
$ kpatch-build patch

ERROR: kpatch build failed. Check /tmp/kpatch-build-1398711757.log for more details.
I'm not sure if I tried to recreate this issue before "fixing" it. @jpoimboe can you recreate after reverting the fix?

Yeah, that's really weird, I'm not able to recreate either. I guess it must have been user error somehow. So we can revert that commit.
