Ok, I see. I am planning to do the following:
I will extract all patches sent to us in the last two decades and
compare it with the actual version and put in a directory for someone to
inspect. (I have to think about the details)
The case I had in mind was (that is anyhow very short but just to
emphasize my point)

`----
But we removed *all* calls to the post-command-hook in the current
matlab.el version and that is why I think, the current version is *not*
derivative work of this particular patch.
But as I said, there will be more complicated cases
