Issues in the master branch

[Ergus]

Hi:

I am using the master branch and I just found 2 errors that I don't
know if they are related, but I haven't seen them before (and are not
there in emacs 26)

1) Some commands are giving this error:

invalid-function with-connection-local-variables.

This happen to me in external commands like ggtags, counsel-rg and some
others.

2) Internal commands like rgrep are producing a wrong output they are
printing the output but with the scape sequences instead of the colors.

I am of course using emacs -Q.

The issues are not there in emacs-26, only in the master; but I have
moved back in the history and I don't find yet where this started to happen.
