PEP 292 classes Template and SafeTemplate are added to the string module. This patch includes test cases and documentation updates, as well as NEWS file updates. This patch also updates the sre modules so that they don't import the string module, breaking direct circular imports.

Many updates to PEP 292 templates. Summary: - Template no longer inherits from unicode. - SafeTemplate is removed. Now Templates have both a substitute() and a safe_substitute() method, so we don't need separate classes. No more __mod__() operator. - Adopt Tim Peter's idea for giving Template a metaclass, which makes the delimiter, the identifier pattern, or the entire pattern easy to override and document, while retaining efficiency of class-time compilation of the regexp. - More informative ValueError messages which will help a user narrow down the bogus delimiter to the line and column in the original string (helpful for long triple quoted strings).

Fix bug in passing tuples to string.Template. All other values (with working str() or repr()) would work, just not multi-value tuples. Probably not a backport candidate, since it changes the behaviour of passing a single-element tuple: >>> string.Template("$foo").substitute(dict(foo=(1,))) '(1,)' versus '1'

Fix small bugs in Template code. * The parameterization of "delimiter" was incomplete. * safe_substitute's code for braced delimiters should only be executed when braced is not None. * Invalid pattern group names now raise a ValueError. Formerly, the convert code would fall off the end and improperly return None. Beefed-up tests. * Test delimiter override for all paths in substitute and safe_substitute. * Alter unittest invocation to match other modules (now it itemizes the tests as they are run).

def test_delimiter_override(self):
SF patch #1056967, changes the semantics of Template.safe_substitute() to not raise a ValueError for dangling delimiters (the delimiter itself is returned).

Fix small bugs in Template code. * The parameterization of "delimiter" was incomplete. * safe_substitute's code for braced delimiters should only be executed when braced is not None. * Invalid pattern group names now raise a ValueError. Formerly, the convert code would fall off the end and improperly return None. Beefed-up tests. * Test delimiter override for all paths in substitute and safe_substitute. * Alter unittest invocation to match other modules (now it itemizes the tests as they are run).

PEP 292 classes Template and SafeTemplate are added to the string module. This patch includes test cases and documentation updates, as well as NEWS file updates. This patch also updates the sre modules so that they don't import the string module, breaking direct circular imports.
