read-print: Define forms for which \n, \t, etc. are not escaped.
Previously, the pretty-printer would unconditionally leave everything but double-quotes and backslashes unescaped when rendering a string. With this change, the previous behavior only applies to forms listed in %NATURAL-WHITESPACE-STRING-FORMS. * guix/read-print.scm (%natural-whitespace-string-forms): New variable. (printed-string): New procedure. (pretty-print-with-comments): Use it instead of 'escaped-string'. * tests/read-print.scm: Add test.
