Hi Ihor,

Thank you for your comments once again. I've changed string= to eq and
it appears to be working OK.

I've also renamed "title" variable to "title-prop" for better
readability. The -prop suffix should show the reader that it was
extracted from the file, and thus cost some CPU/IO.

I've attached an updated version to this email. Would love to hear what
you think.

Subject: [PATCH 1/5] org-agenda.el: customize outline path in echo area

* lisp/org-agenda.el (org-agenda-show-outline-path): add an option to
show document title in outline path (instead of file name)
* lisp/org.el (org-get-title-from-file): a function to collect the
document title from the org-mode file
* lisp/org.el (org-display-outline-path): add logic that will collect a
document title and put it into the outline path if
org-agenda-show-outline-path set to 'title
