Subject: Add a new API:
X-Git-Tag: v2.1b1~120
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=9e2631897539a95f1413df00847544487fb3b827;p=thirdparty%2FPython%2Fcpython.git

Add a new API:

    warn_explicit(message, category, filename, lineno, module, registry)

The regular warn() call calculates a bunch of values and calls
warn_explicit() with these.

This will be used to issue better syntax warnings.
