Think about the various Help commands, such as 'apropos': they show
the doc strings or just their first sentence entirely out of any
context.  Users who invoke such commands should be capable to
understand at a glance whether the command/variable is something they
should examine further.  So having important keywords in there helps
immensely to make such triage steps much faster and more efficient.

Yes, thanks.  My suggestion is a very minor variation of the latter:

 Format spec for imenu's display of section titles from docview documents.
