(org-w3m-get-image-end): New function, for w3m-img links.
3] As mentioned in the patch, and in the commit message, there seem to
be several functioned unused in the code base that could be
candidates for removal...
org-w3m-get-anchor-start
org-w3m-no-prev-link-p
org-w3m-get-prev-link-start
4] Additionally, in performing the merge I came across function
org-string-nw-p, which seems to be an unnecessary duplicate of the
emacs core function string-blank-p. It may be that historically you
once needed your own home-made functions/macros, but now that emacs
core has them, you may want to consider a refactor.
