Description of problem:
python-TestSlide fails to build with Pygments 2.14 we want to bring to Rawhide. 
It's likely related to some output changes brought by new Pygments. I checked the impact in a copr repository, see links below.

Version-Release number of selected component (if applicable):
2.7.0-7

How reproducible:
Always

Steps to Reproduce:
$ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/pygments-2.14/fedora-rawhide-x86_64/ --no-clean your.src.rpm
$ mock -r fedora-rawhide-x86_64 --addrepo=https://download.copr.fedorainfracloud.org/results/ksurma/pygments-2.14/fedora-rawhide-x86_64/  shell

Actual results:
https://download.copr.fedorainfracloud.org/results/ksurma/pygments-2.14/fedora-rawhide-x86_64/05362858-python-TestSlide/builder-live.log.gz
