Issue 5754: tweak shelve doc wording to make it clearer that even when
writeback=True values are written to the backing store when assigned to
the shelf. Add test to confirm that this happens. Doc patch and added
test by Robert Lehmann. I also fixed the cross references to the sync
and close methods.

Improve issue 7835 fix per MAL to handle the case that the
module dictionary has also been cleared.

Issue 7835: Shelve's __del__ method calls its close method, and its
close method refers to an identifier in the global module namespace.
This means that when __del__ is called during interpreter shutdown (if,
for example, the calling program still has a pointer to the shelf),
sometimes that global identifier would wind up being None, causing
mysterious 'ignored' exceptions. This patch checks for the possible None
value first before using the global, thus avoiding the error messages.

this can result in significantly smaller files. All classes as well as the
open function now accept an optional binary parameter, which defaults to
False for backward compatibility. Added a small test suite, updated the
libref documentation (including documenting the exported classes and fixing
a few other nits) and added a note about the change to Misc/NEWS.
also modified check_all function to suppress all warnings since they aren't
relevant to what this test is doing (allows quiet checking of regsub, for
instance)
"self.dict.close()" and ignore the exception. The "if self.dict:"
part would be calculated through len(self.dict.keys()), which is very
expensive for a large dictionary...
pickle.py: new low-level persistency module (used to be called flatten)
dbmac.py: stupid dbm clone for the Mac
anydbm.py: generic dbm interface (should be extended to support gdbm)
