[Zope-Checkins] CVS: Packages/BTrees/tests - testBTrees.py:1.51.8.4

[Tim Peters]

Update of /cvs-repository/Packages/BTrees/tests
In directory cvs.zope.org:/tmp/cvs-serv4422/BTrees/tests

Modified Files:
      Tag: Zope-2_7-branch
	testBTrees.py 
Log Message:
Backport from ZODB 3.4.

Collector 1843:  IISet.keys: bad exception handling.

Bucket_rangeSearch():  De-obfuscated the calls to
Bucket_findRangeEnd(), so that they stop ignoring
the latter's error returns (a mind-bending combination
of embedded assignment nested in an UNLESS macro,
seemingly copy+paste'd so that the error occurred twice).
