I don't know - my assumption was that within emacs, it would be
basically just another type of emacs buffer, and be a legitimate subject
for all elisp commands.
Your question got me thinking, that emacs may have subtle rendering
quirks, so just now, I opened fresh instances of info buffers in both
very wide and very narrow windows, and they both `fill' to the same line
length, ie the wide window has a lot of right-side white-space, and the
narrow window has lines wrapped.
Since I submitted the bug report, I've continued trying to get the
feature working, and have been experimenting with the org-mode hooks
`org-create-file-search-functions' and
`org-execute-file-search-functions' to no success. The only, supposedly
working examples I've come across for these functions are [1] and [2].
If you know of other resources, that could be helpful.
One other possible related bug I've found is that when trying to use
org-store-link for a particular line number within an org-file, the link
is created to the most recent header. One can successfully, manually,
hack the created link, replacing the reference to the header with a line
number, in order to be able to navigate directly to the desired line
(all this, for a link target in an org mode file - this was done as a
test, once I came across the original bug) [3].
