Hm, yes, that's a good point.
Here's another proposal: what if we split overview_getheader into two
functions, one that retrieves only mandatory headers and one that
retrieves only extra headers? Then the first can take an index and the
second can take a header, and the second wouldn't ever bother to call
overview_index() and would just walk the extra headers.
If for other call sites we really want a simple function that does the
work of returning whichever type of header, we can always write it as a
wrapper around those two functions.
