Hi,

In the following thread

Ihor Radchenko. Re: Exporting elisp: and shell: links.

it was discussed that attempts to customize export to plain text of link 
types such as "elisp:" and "shell:" break formatting as notes at the end 
of the heading (`org-ascii-links-to-notes').

The attached patches is a draft implementing this feature (new functions 
are not documented yet).

For ascii backend :export function from `org-link-parameters' may return 
(PATH . DESCRIPTION) `cons' instead of string. Depending on chosen link 
style it will be exported as "[DESCRIPTION]" with the "[DESCRIPTION] 
PATH" note at the end of heading or as the inline reference "DESCRIPTION 
(PATH)".

I believe that parenthesis should be skipped in the case of angle 
brackets "(<URI>)", but I do not change this behavior. There is some 
inconsistency in respect to brackets for description of inline links, 
but it is preserved as well.

I do not like that :export functions are called twice: for text and for 
note. In my opinion it is better to collect links in a property of INFO 
to later format notes at the end of the heading. I would consider more 
dense style of notes with list markers instead of empty line as separator.

Namely "shell:" and "elisp:" links may be exported as notes in the 
current Org version since they have no :export property. The proposed 
feature allows to have custom :export e.g. to not add "shell:" prefix to 
the code.
