[tex-live] How to disable the automatic line break at 80 characters in the output of pdflatex?

[Karl Berry]

    But this does not work adding lines to the end of the texmf.cnf file:

Add the lines to the beginning of the file.  Or, much preferable, add
them to the local file /usr/local/texlive/2014/texmf.cnf
instead of the system-distributed file
/usr/local/texlive/2014/texmf-dist/web2c/texmf.cnf.
