Re: [O] org-insert-link with HTML title as default description

[Miro Bezjak]

Hi Sylvain, Bastien,

I have indeed noticed `org-make-link-description-function'. Though,
from its documentation I've somehow concluded that it makes the final
(and not default) description. By rereading documentation and source
code for `org-insert-link', it appears that with addition of Sylvain's
patch I could indeed use `org-make-link-description-function' and not
wrap around `org-insert-link'.

Cheers,
Miro

P.S. I'm sending SSH public key in a separate mail.
