Subject: 26.1; next-error does not go to correct column for grep

This is a regression from 25 which has the correct behaviour.

emacs -Q
C-x C-f /tmp/hello
Hello
C-x C-s
M-x grep
C-a C-k grep --color -nH --null -e ll /tmp/hello
C-x `

This puts the mark in column 0, not in column 2, even though "ll" is
highlighted in the *grep* buffer.

This is a regression in 26.1, it used to work in 25.

To fix it in my local copy, I edit grep-regexp-alist in grep.el. There
are two instances of 'grep-match-face which I replaced with an unquoted
grep-match-face.
