As far as I can tell, this comes from:

(defun completion-basic-try-completion (string table pred point)

[...]

      (let* ((suffix (substring afterpoint (cdr bounds)))
             (prefix (substring beforepoint 0 (car bounds)))

But the length of beforepoint (i.e., "./nosuchcomma") is 13, while (car
bounds) is 14.

I'm not sure how this all connects up, so I've added Stefan to the CCs.
