(info "(emacs) Grep Searching") says
Your command need not simply run ‘grep’; you can use any shell
command that produces output in the same format. For instance, you can
chain ‘grep’ commands, like this:
grep -nH -e foo *.el | grep bar | grep toto
OK, but it also needs to mention:
To have this currently work, be sure to remove the "--null" currently
added to today's prompt,
Run grep (like this): grep --color -nH --null -e
Else you will end up with
Binary file (standard input) matches
emacs-version "27.1"

I don't think the manual can warn you about all invalid things a user
may decide to put in the command line. The --null is part of the
default command line, so I see your point, but I don't think mentioning
this stuff in the user manual would make much sense, and I'm closing
this bug report.

I'll make the change for you.
But I checked on
https://www.gnu.org/software/emacs/
https://www.gnu.org/software/tasklist/howto-volunteer.html
and can't find where I can edit the source (hopefully like it is easy to do on
GitHub too.)
