    [groff]: Improve portability of a test.
    
    * src/roff/groff/tests/regression_savannah_58153.sh: Improve
      portability.  Avoid the unpredictability of implementations when
      putting backslashes inside a groff-piped printf shell command inside a
      here document inside a command substitution by changing the groff
      escape character to something meaningless to the shell and to printf
      ('@').  Fixes a test failure on Solaris 11.
