To me, the context is that this is read by a user of the functionality,
wanting to fine-tune it (i rarely start exploring a functionality by
reading the docstring of one of its customizable variables).

Barring that: the Imenu section of the manual calls the items being
formatted here simply "definitions".  If we assume that the user knows
about imenu in general, one could have:

   "Format string for the imenu definitions extracted from documents."

Or, perhaps, trying to provide the missing context for not-yet-users:

   "Format string for the section titles extracted by imenu from docview 
documents."

Any better?

Sounds better to me too, yes.

Thanks,
