Expose some buffer related functions

[doronbehar]

Hi!

I really enjoy this plugin. I just wrote a customization to the :Buffers command I shared at https://github.com/junegunn/fzf/wiki/Examples-(vim)#delete-buffers-from-buffers and this requires these small changes. I hope it'll be OK with you.

Regards.

See my previous comment: #1024 (comment)

Making things public means that I'll have to pay extra care not to break backward compatibility from then on, and I don't want to do it and I want to make it clear by naming these functions with _ prefix.

Done 🎸.

Hi @doronbehar

I encounter an error when I run the customized version of :Buffers command and try to delete a buffer using D. I attached the screenshot below. Thank you.

Yea I know, another person has contacted me personally to note this fault. However, from my experience these errors are not consistent - they don't appear always and they are not always reproducible, at least for me.

The problem is, that when D is pressed, we want to change something both in "the parent" Nvim session and in the list of open buffers in fzf "the child". This makes it hard to decide whether D should be mapped to something by an autocmd (By Vim) - which will make it easy to delete buffers with it, or to use fzf's --bind. In the current implementation, the latter choice was made.

I'm currently unavailable to solve this little quirk, though it's in my TODO now. I will find the time probably at the end of July, when my semester will over.

P.S, sorry @junegunn for abusing your repo to discuss this.

Okay. I think it is better to give a tag/mark like "bug" to this customized command in the wiki page so that other users could recognize it and wait for it being solved. Thanks.

I've removed the wiki section as I've reached the conclusion it'll be impossible to implement this idea without the feature described in junegunn/fzf#2019 .
