Subject: gh-79964: Clarify the imaplib fetch example in the docs (GH-152780)
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=50ae0be74988564fb09746a49eb4b8f8e740f3c3;p=thirdparty%2FPython%2Fcpython.git

gh-79964: Clarify the imaplib fetch example in the docs (GH-152780)

A FETCH response may contain additional or unsolicited data, so the
message is not always data[0][1].
