OK.

In git (branch emacs-25), the docstring of outline-hide-sublevels is only:
"Hide everything but the top LEVELS levels of headers, in whole buffer.
This also unhides the top heading-less body, if any.

Interactively, the prefix argument supplies the value of LEVELS.
When invoked without a prefix argument, LEVELS defaults to the level
of the current heading, or to 1 if the current line is not a heading."

In my understanding, this still does not fully document the behavior
of actively revealing all headers up to level LEVELS.  The docstring
of outline-hide-other is also incomplete in this sense because it does
not fully document that it actively reveals the body of the current
entry (it then becomes visible even if it was previously hidden).

The manual says:
    Run ‘occur’ using the search string of the last incremental string
    search.  You can also run ‘M-s o’ when an incremental search is
    active; this uses the current search string.

If I understand English correctly (I am Brazilian) the first sentence
cited above says that if you run an incremental search, exit it (e.g.
by pressing RET), and later type M-s o, it will automatically run
‘occur’ using the search string of the last incremental string search.

I mean the fact that, in that case, "dabbrev searches all the other
buffers, except those named in ‘dabbrev-ignored-buffer-names’, or
matched by ‘dabbrev-ignored-regexps’." (according to
dabbrev-check-all-buffers docstring).

Thank you very much for improving Emacs!
@Drew: you are welcome.
