Subject: [PATCH 1/2] org-agenda.el: allow to customize outline path in echo
 area

Some of the org-mode data bases auto-generate file names, so they don't
carry a lot of information and can be noisy. Allowing user to show
document titles instead could be useful. Showing titles is disabled by
default.
