Subject: _parsebody(): When adding subparts to a multipart container, make sure
X-Git-Tag: v2.3c1~6776
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=15e9dc9eac219775aa70e57652810a187584d7c6;p=python

_parsebody(): When adding subparts to a multipart container, make sure
that the first subpart added makes the payload a list object.
Otherwise, a multipart/* with only one subpart will not have the
proper structure.
