Bug#926392: licensecheck chokes on long lines

[Sandro Mani]

Package: licensecheck
Version: 3.0.36

As reported downstream at [1]:


$ wget 
https://files.pythonhosted.org/packages/source/x/xonsh/xonsh-0.8.12.tar.gz
$ tar xf xonsh-0.8.12.tar.gz
$ licensecheck xonsh-0.8.12/xonsh/parser_table.py

=> Licensecheck hangs eating cpu cycles (the file has lines with 33k and 
71k characters).
