Your explanation makes sense and setting properties on the string used
for the line-prefix/wrap-prefix does indeed produce the desired result
(thanks!).

Perhaps I should update the bug to read 'why is the line-prefix at point
== 1 shown with the properties of the following character', though. Is
there special code for handling that case?
