Patch submission guidelines are found at http://www.python.org/dev/patches/

Since patches are made for the py3k branch, some matches in Henri’s grep won’t get patched: bsddb, compiler, posixfile and rexec have been removed.  The person that will commit the patch will have to edit those too when merging into 2.7, unless a kind soul provides one patch per branch (not a requirement).

Last remark: tempfile is a false positive; editing old whatsnew is not worth it IMO.
