Hi.

as org-mode knows a command `org-show-entry' looked for
`org-hide-entry', but couldn't get it.

So here it is.

Are you going to use it in org-mode code base in future?

Thanks and Regards

This will leave the buffer in a pretty messy state.

It will hide a headline and the text below it, but not the subtree.   
The ellipsis will be on the text belonging to the entry before.

For example

* test
   aaa
** sub 1
    bbb
** sub2
    ccc

Call this command on sub one, and you get

* test
   aaa....
** sub2
    ccc


This is not good.  So I don't understand what this might be useful for.
Maybe there are outline-... commands which do what you really mean?

Indeed, thanks. It's cured already.
Please try patch attached.

Hi,

telling the future is hard.
Concerning the present state, I'd say programm should follow certain 
rules, meet expectations.

Which one is hard to say again. So it's rather my personal view: if a 
forward- function exists, I expect a backward-.

If hide-something exists I expect show-something.

And so on.

With Emacs in general it's better to expect the uncommon rather than the 
common, but why not have both?

Yours

Andreas

I still think this does something bad to the buffer.....
