[New-bugs-announce] [issue2772] Add PendingDeprecationWarning for % formatting

[Eric Smith]

New submission from Eric Smith <eric at trueblade.com>:

Per http://mail.python.org/pipermail/python-3000/2008-April/013094.html,
add a PendingDeprecationWarning to 3.0 for % formatting.

The attached patch implements this for 3.0.  For 2.6, it should only be
a PendingDeprecationWarning if -3 warnings are turned on.  I'll work on
that after the 3.0 patch is accepted.

I'm not wild about using a global variable to disallow recursion, but
it's probably the way to go.  Question:  Do I need to acquire the GIL here?

Another issue is that the interpreter should probably at least start up
without triggering these warnings.  I'll add an issue for that at a
later date.
