They aren't ignored. And the documentation already covers this issue, on 
its very first page:

https://www.gnu.org/software/grep/manual/html_node/Introduction.html

This says, "If the final byte of an input file is not a newline, grep 
silently supplies one."

I doubt whether this minor issue should be covered in the man page, as 
it is merely a brief summary of the documentation.
