pep-0237.txt
Log Message:
Remove author's email addresses.
Mention %X (same treatment as %x).
Insert new stage B0, which gives warnings about e.g. 0xffffffff
without semantic changes. Move the proposed deployment of subsequent
stages up by one minor revision.

+ numeric outcome in stage B1, in particular hex() and oct(),
+ '%u', '%x', '%X' and '%o', hex and oct literals in the
+ (inclusive) range [sys.maxint+1, sys.maxint*2+1], and left
+ shifts losing bits; but not repr() of a long.

B1. The remaining semantic differences are addressed. Operations
that give different results than before will issue a warning
