master 52528d6: Print newlines as \n instead of \12 in ERT results

[Mattias Engdegård]

branch: master
commit 52528d6a162630a57ec0dd182295b4ce2c4c228d
Author: Mattias Engdegård <mattiase@acm.org>
Commit: Mattias Engdegård <mattiase@acm.org>

    Print newlines as \n instead of \12 in ERT results
    
    This makes test errors unquestionably more readable.  The change also
    makes FF print as \f; other controls still use octal escapes.
    
    * lisp/emacs-lisp/ert.el (ert--pp-with-indentation-and-newline):
    Run `pp` with `pp-escape-newlines` set to `t`.
