Subject: [PATCH] Kill in eww and keep the links for org

Hi,
to kill in a w3m-buffer and yank into an org-mode-buffer by keeping the
links is a long known feature in org-module org-w3m. The patch below
provides this functionality for eww. Note that the code is very similar
to the code for the w3m case.
What do you think? Shall I try to push the code?
Ciao, Marco

Subject: [PATCH] org-eww.el: Special kill in eww for Org for keeping the links
* contrib/lisp/org-eww.el(org-eww-copy-for-org-mode): Realization of
the kill.
(org-eww-goto-next-url-property-change,
org-eww-no-next-link-p, org-eww-url-below-point,
org-eww-url-below-point-p): Auxiliaries for accessing a eww buffer
The code has emerged from the very similar org-w3m.el.
