diff Objects/bytesobject.c @ 74415:050c07b31192 3.2

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Consolidate the occurrances of the prime used as the multiplier when hashing to a single #define instead of having several copies in several files. This excludes the Modules/ tree (datetime and expat both have a copy for their own purposes with no need for it to be the same).
