1. a_Transaction_object.begin() is deprecated.  Don't use it.

2. Commit failure is "sticky" now:  the current transaction
   must be explicitly discarded (abort() or begin()) before
   a commit can succeed again.

Collector #1457: ZCTextIndex's QueryError and ParseError are now available for import from untrusted code.

     - Collector #1491: talgettext.py did not create a proper header
       for the generated .pot file if multiple pagetemplate files
       were processed.

- Updated to use transaction.commit() rather than
  get_transaction().commit()

       same signature as str.strip()

dd Michael Dunstan's "explicit abort after error propagates into publisher" patch as documented in http://zope.org/Collectors/Zope/789 and as required by recent changes to ZODB which prevent a connection from being cleanly closed if modifications are extant in that connection.

     - Collector #1267: applied patch to fix segmentation faults on 
       x86_64 systems

On a tip from Dieter, ensure that our hasattr replacement doesn't invoke __len__ on objects retrieved by getattr due to Python boolean magic!

I wish a miserable plague upon boolean magic that calls __len__ and the exception-hiding behavior of hasattr.
