Well, as you yourself show, it is not the "same problem".

I did, that's why I asked.  I wanted to know that we see the same
phenomenon.

(And btw, there's no need to load cygwin-FOO.el to see the problem.
Just "M-x grep RET "#" *.el" is enough.  It is also repeatable on
GNU/Linux.)

Exactly!  Customize grep-highlight-matches to nil, and the problem
goes away.

That's Grep in action, when we ask it to highlight matches in its
output.  It does that by inserting ANSI escape sequences.

Not me, but hopefully someone else.
