Yes, the two whitespaces on the wrapped line seem to be necessary to
trigger the bug.

I came across this while editing a LaTeX document, and the two white
spaces that triggered the bug were the usual two spaces after a full

after the Emacs 24.4 release, but didn't manage to get a reproducible
recipe until now.
