This sounds sensible, but I'm not sure whether it's worth complicating
the patch by adding checks for this new user option in `eval.c`,
`debug.el` and `edebug.el`.

How do you plan on informing and surveying users?  Would a discussion on
emacs-devel be the way to do this or do you have something different in
mind?

It's a complication, sure.  But it doesn't sound too complicated, and
given the fears of breaking someone's code, I think it's justified.

I thought just watching the discussions and the bug tracker would be
enough.  Then, a couple of releases from now, we could ask whether
making it the default would be okay, and see how people react.

I like this idea :) In that case, we should probably mention the options in NEWS, adding a note that code should be updated.

I third the appreciation of having a user option.

Does this still happen in Emacs 26?  What version of grep do you use?
Does the string you're grepping for matter?  Do the file names matter?
Can you reproduce this from 'emacs -Q'?

Hmm, that forwarding didn't work out.  It was supposed to say:

    actually, in the version 25.3.1, the function work well again .
