[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan <tir.karthi at gmail.com>:

Following warnings are caused in Doc/tools/extensions/peg_highlight.py . These warnings show up during doc builds since the extension is used in the build. This is an easy issue to fix.

./python -Wall -m py_compile /root/cpython/Doc/tools/extensions/peg_highlight.py
