Subject: [PATCH] * (bug 32617) Fix for edit summary on section 0 containing a
 bogus section heading

Based on patch posted by Dan Collins: https://bugzilla.wikimedia.org/attachment.cgi?id=9552
with a tweak to avoid breaking a similar case in other sections. Follows up on function extraction & test cases added in r105379.
