This update fixes the following issues with python3-pyparsing:
- bnc#853270: update to 2.0.1
* Removed use of "nonlocal" that prevented using this version of pyparsing with Python 2.6 and 2.7. This will make it easier to install for packages that depend on pyparsing, under Python versions 2.6 and later. Those using older versions of Python will have to manually install pyparsing 1.5.7.
* Fixed implementation of <<= operator to return self;
