Hi,

Consider the following example:

--8<---------------cut here---------------start------------->8---
(with-temp-buffer 
  (require 'ox-ascii)
  (insert
   "- [[http://www.npr.org/blogs/monkeysee/2009/03/a_very_long_url_makes_a_very_s.html][A label with a long link]] :: Lorem ipsum dolor sit amet, consectetur adipiscing elit\n")
  (org-ascii-export-as-ascii nil nil nil t))  
--8<---------------cut here---------------end--------------->8---

With output:

--8<---------------cut here---------------start------------->8---
[A label with a long link]: Lorem
                            ipsum
                            dolor
                            sit
                            amet,
                            consectetur
                            adipiscing
                            elit


[A label with a long link]
http://www.npr.org/blogs/monkeysee/2009/03/a_very_long_url_makes_a_very_s.html
--8<---------------cut here---------------end--------------->8---

The reason for the wrong formatting is that org-ascii--current-text-width
takes that there's is like -28 characters left for lorem ipsum...  It does
that because it counts link and label.

The patch fixes this by only counting the length of the label.

I'm not really familiar with the ascii backend, so let me know if there's
any obvious deficits that I have overlooked.

Otherwise I push it.

Thank you. I have applied a slightly different patch.

The formatting is still not optimal, however, as you can end up with
something like

  [http://www.npr.org/blogs/monkeysee/2009/03/a_very_long_url_makes_a_very_s.html]: Lorem
                                                                                    ipsum
                                                                                    dolor
                                                                                    sit
                                                                                    amet,
                                                                                    consectetur
                                                                                    adipisicing
                                                                                    elit

A proper formatting would be, for example,

  [http://www.npr.org/blogs/monkeysee/2009/03/a_very_long_url_makes_a_very_s.html]:

        Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed do
        eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut
        enimad minim veniam, quis nostrud exercitation ullamco laboris


I guess a threshold would then be needed, though, as the following is
still nice and probably desirable

  lorem: Lorem ipsum dolor sit amet, consectetur adipisicing elit, sed
         do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut
         enimad minim veniam, quis nostrud exercitation ullamco laboris nisi

But I'm not sure if it is common to have such long tags in description
lists.

I don't know.  If it is, maybe someone will complain.
