Subject: Add a note that this file should be kept compatible with Python 1.5.2,
X-Git-Tag: v2.3c1~3244
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=919000e9ec36c513f08253091b71a3aead2aff08;p=python

Add a note that this file should be kept compatible with Python 1.5.2,
per PEP 291 (although there are currently string methods used).

This patch makes it compatible with 2.2, at least, by detecting
universal newline support.
