I don't follow...

Any identifiable sections that are not derived from the original commit can 
presumably be kept, though determining the proper license status of contributed 
code without an explicit copyright statement[1] is fuzzy enough in the absence 
of a bad license being present on the file being contributed to.

[1] I don't trust signed-off-by; I imagine many use it without ever having read 
what it was supposed to mean in a different project, especially when git 
automates it with a simple flag.  That seems more likely to be a practical 
problem than "all rights reserved"...

Calm down...

I did write an e-mail to the person that submitted the code (it's the thread 
we're replying to) and claimed that copyright.  I assumed that would be the 
person with the best knowledge of whom to contact in that company.  If you want 
to find the right person to contact without his help, go ahead -- but that seems 
like more work to me than rewriting a relatively small chunk of code.

Especially since, as you note, big chunks of the file are not from that original 
commit, and what was in the original commit may have come from another upstream 
project.
