Note:

To support what Dave's E-mail client does, and what Pine, Mulberry and
others seem to be doing, we could also make it possible (or optional) to
fill up gaps in the summary with dummy items that contain "..." for all
string fields.

This will make adding summary items out-of-order to the summary a little
bit slower (assigning a few more pointers to make them point to such a
dummy item).

Having a dummy entry in the data-file and index file makes few sense as
we store strings uniquely in the mmaped file anyway (you'll see a "..."
string at the top of the file somewhere).

But it's certainly a possibility ...
