Sure. Sorry for not doing it earlier. For some reason, I assumed that this was
obvious.

Here's the reproducer (built from the latest commit on the emacs-28 branch):

  1) mkdir /tmp/test
  2) cd /tmp/test/
  3) git init
  4) echo data > file.txt
  5) git add file.txt
  6) git commit -m "first commit"
  7) emacs -Q
  8) <run shell and cd /tmp/test>
  9) <execute C-x v L>
  10) <hit RET on the first commit>

This is what I see on my system (I hope that gmail doesn't remove the escapes):

  first commit

It might be dependent on git configuration, but I think it's safe to assume that
there might be escape sequences and simply use --no-color. And that's what
my patch does.
