I discovered a more-artificial case where grep messes up even on modern 
platforms, namely 'grep -f - -f -' where grep essentially ignores the 
second '-f -'. I installed the attached to fix that, along with another 
bug where grep wasn't reporting fclose errors.

I think these bugs are so unlikely and artificial that they're not worth 
mentioning in NEWS.

As a side effect, this patch might fix the bug#50129 problem on your old 
platform. Hard to say.
