bug#37163: 27.0.50; grep command no colors

[Ergus via Bug reports for GNU Emacs, the Swiss army knife of text editors]

--text follows this line--

In the current emacs master breanch I am trying to use the grep command
and the execution is fine but the output *grep* buffer doesn't contain
the colors, it shows the scape sequences.

I have tried in my actual installation of emacs 26 and the issue is not
there, only in emacs 27. In gui and tui the behavior is the same.

Example:

M-x grep REP
grep --color -nH --null -e display xdisp.c

I cannot reproduce this with today's master.  Do you still see this?

Hi Eli:

After the make bootstrap this was fixed too. I will close the bug report.
