[nongnu] elpa/cider ab54769d51 1/2: Replace newline chars with newlines in test report

[ELPA Syncer]

branch: elpa/cider
commit ab54769d5171c06f12034156b834ed7c95d29d0c
Author: Lars Andersen <expez@expez.com>

    Replace newline chars with newlines in test report
    
    When the library / app under test returns long error messages on test
    failures it will often include newlines.  These are today displayed as
    `\\n` and we get an error message on one very long line.
    
    This commit turns these newline characters into actual newlines, which
    makes the content of the `*cider-test-report*` buffer much more pleasant
    to read.
