Since by default (which we don't override) an index entry points to its
nearest containing section (rather than directly to its occurence), if a
section contains the same index entry more than once, it does indeed look
like a duplicate on the outside. There are at least two obvious ways to
get rid of the warnings, but I could never figure out the benefits and
drawbacks of them.
