OK, that was it, thanks. I had

(add-hook 'org-tab-first-hook 'org-insert-link-maybe)  

I believe org-insert-link-maybe (code below) is something that Eric
threw together: am I right in thinking it has not been incorporated into
org core?

In any case, could someone help me with the regexp problem I encountered
when I tried to improve it? Here's the original version

--8<---------------cut here---------------start------------->8---
  (defun org-insert-link-maybe ()
    "insert a file link depending on the context"
    (let ((case-fold-search t))
      (if (save-excursion
            (when (re-search-backward "[[:space:]]" nil t) (forward-char 1)
                  (looking-at "\\[?\\[?file:?")))
          (progn (replace-match "") (org-insert-link '(4)) t)
--8<---------------cut here---------------end--------------->8---

I want to (a) restrict it to looking at the current line and (b) not
allow it to match words like 'filepath'. This seems to be almost there

--8<---------------cut here---------------start------------->8---
(defun org-insert-link-maybe ()
  "insert a file link depending on the context"
  (let ((case-fold-search t))
    (if (save-excursion
	  (looking-at "\\[?\\[?file:?[ \t\n\f\v\r]"))
	(progn (replace-match "") (org-insert-link '(4)) t)
--8<---------------cut here---------------end--------------->8---

But this doesn't match 'file' followed by end-of-buffer. I want a
character class that matches any of
{space,tab,newline,end-of-buffer}. How do I do that? It seems that
although "\\'" matches end-of-buffer, it doesn't work in a character
class ("[\\']")?
