[Python-Dev] Code cleanups in stable branches?

Hi,

http://hg.python.org/cpython/rev/72de2ac8bb4f branch: 2.7 user: Petri Lehtinen <petri@digip.org> date: Sun Oct 30 13:55:02 2011 +0200 summary: Avoid unnecessary recursive function calls (closes #10519)

http://hg.python.org/cpython/rev/0694ebb5db99 branch: 2.7 user: Jesus Cea <jcea@jcea.es> date: Mon Oct 31 16:02:12 2011 +0100 summary: Closes #13283: removal of two unused variable in locale.py

I thought that patches that clean up code but don’t fix actual bugs were not done in stable branches. Has this changed? (The first commit quoted above may be a performance fix, which would be okay IIRC.) Regards
