It does happen a bit in practice. It's nailed me a few times. I just
consider it as the way git works and didn't complain.

I just brought this up here:

 http://lkml.kernel.org/r/20180112121148.20778932@xxxxxxxxxxxxxxxxxx

And someone replied with a pointer to:

 https://github.com/git/git/blob/master/Documentation/RelNotes/2.0.0.txt

suggesting 

   git config commit.cleanup scissors

Where git looks for:

 # ------------------------ >8 ------------------------

and does not delete comments before it. But this could play havoc when
doing squash though.
