[O] Behavior of `org-show-entry'

[Eric Abrahamsen]

I do a lot of my Org navigation with `helm-org-in-buffer-headings' and
`helm-org-agenda-files-headings', which prompt you for an org heading,
then take you there.

I'm always annoyed that, once you're at the heading, it leaves it in
a half-open state where you can see the immediate text of the target
entry, but all of its child entries are replaced by an ellipses.

* Target Heading
  Drawers and text
  ... # ellipses instead of child headings
* Next Heading

You then have to hit <tab> twice to see the children.

The helm commands end by calling `org-show-entry', which first does
this:

(outline-flag-region
 (max (point-min) (1- (point)))
 (save-excursion
   (if (re-search-forward
        (concat "[\r\n]\\(" org-outline-regexp "\\)") nil t)
       (match-beginning 1)
     (point-max)))
  nil)

Which leaves the heading in the state described above, and then does
this:

(org-cycle-hide-drawers 'children)

Which has no effect.

I'm not really sure what the purpose of `outline-flag-region' is, but
I'm pretty sure this isn't the desired effect. The call to
`org-cycle-hide-drawers' should reveal children, isn't that right?

Which part of this should be tweaked to achieve the desired effect?

Thanks!
