Summary: Support for case-insensitivity in string.Template

Initial Comment:
Python's $-style templating is wired for optional
case-insensitivity under the hood, but doesn't expose
this via the API. The attached patch (against trunk/
r50813) adds a new optional argument to turn this
behavior on, and includes doc and tests.

Yes, that would be much more acceptable!

Thanks for your responses, all.

The problem is kws: you can't customize it from the outside
like you can the mapping argument. If we replaced _multimap
with mapping.update(kws), then we'd have our hook and I
think I'd be satisfied.

Would you be any more psyched about that patch? :)

I'm not psyched about the patch.  First, I've always thought
that case insensitivity ought to be handled by the mapping
from which the keys are being extracted and by setting the
idpattern.  Second, I definitely don't like adding the
case_sensitive argument to substitute() and
safe_substitute(). Because it lives in the same namespace as
kws it makes for icky rules on resolving any conflicts.

Is there a reason why the existing mechanisms are insufficient?

Barry, is this something you want or is it at odds with the
notion of "simplified templating"?

The patch looks very thorough and complete, I will try to
look into it after 2.5 is out.

Don't let that prevent you reviewing 5 patches, Chad ;-)

I've replaced the patch with one that polishes off a few
bugs and ambiguities, with accompanying tests and doc.

forthcoming.
