Thanks a lot, that was helpful!  I'm starting to feel more and more
confident with org-element-whatever, that's good.

I have one more question.  What I'm about to do is (basically) put
"file:some-file-name::" in front of the link, without changing the
description.  I could use `org-element-put-property' and (AFAIU)
org-element-link-interpreter to put it into the buffer (and probably
delete the old one).  It would be much easier (and maybe faster) just to
go to the point in the buffer where the link starts, go `(forward-char
2)' (past the brackets) and `(insert (concat "file" name "::"))'.

But, is it safe?  Wouldn't it break something?  And is it considered a
good practice?
