Thanks! I can indeed reproduce your findings. The behavior comes from
this snippet of code (part of org.el:org-insert-link):
--8<---------------cut here---------------start------------->8---
...
(cond
(link-location) ; specified by arg, just use it.
((org-in-regexp org-bracket-link-regexp 1)
;; We do have a link at point, and we are going to edit it.
(setq remove (list (match-beginning 0) (match-end 0)))
(setq desc (if (match-end 3) (org-match-string-no-properties 3)))
(setq link (read-string "Link: "
(org-link-unescape
(org-match-string-no-properties 1)))))
((or (org-in-regexp org-angle-link-re)
(org-in-regexp org-plain-link-re))
;; Convert to bracket link
(setq remove (list (match-beginning 0) (match-end 0))
link (read-string "Link: "
(org-remove-angle-brackets (match-string 0)))))
((member complete-file '((4) (16)))
;; Completing read for file names.
(setq link (org-file-complete-link complete-file)))
(t
;; Read link, with completion for stored links.
(with-output-to-temp-buffer "*Org Links*"
(princ "Insert a link.
Use TAB to complete link prefixes, then RET for type-specific completion
support\n")
...
--8<---------------cut here---------------end--------------->8---
The default case is the last one, where the link is read interactively
from the minibuffer with TAB completion on link prefixes, followed by
RET for the type-specific completion support.
When you are editing an existing link, we get into the second cond
clause (the one with the comment " ;; We do have a link at point, and we
are going to edit it.") and that one uses a straight read-string with no
completion.
I suspect that's an oversight. Not sure how easy it is to fix (my hunch
is that it should be easy to transplant the completion code into the
second case, but I don't know for sure).
It seems like a worthy candidate for attention if only for consistency's
sake, but the maintainers will have the last word on that. They might be
more easily persuaded however, if you provide a patch to fix it ;-)
