In fact, in the "/usr/local/texlive/2014/texmf-dist/web2c/texmf.cnf" file, there was already these lines:
error_line = 79
half_error_line = 50
max_print_line = 79

So, I have replaced them by:
error_line=254
half_error_line=238
max_print_line=1000

I have done that instead of adding these lines at the end of the file.
It works fine now.

I have also tried to create the missing "/usr/local/texlive/2014/texmf.cnf" file and adding these three lines but in this case, it does not work.

In fact, as I am on Slackware 14.1, my texlive 20130530 has been patched.
So, my path are maybe not the one of the original texlive 20130530 version.
For example, instead of "/usr/local/texlive/2014/texmf-dist/web2c/texmf.cnf" I have "/usr/share/texmf-dist/web2c/texmf.cnf".
And I thought that instead of "/usr/local/texlive/2014/texmf.cnf" the system-distributed file could be "/usr/share/texmf.cnf".
Maybe my guess is wrong and it explains why it does not work with this system-distributed file.

Is there a way to know where is the system-distributed file?
