I am a bit sad this patch didn’t get applied, but I understand.

But I found this advice on SO: http://stackoverflow.com/a/3141456/89376

#+BEGIN_SRC emacs-lisp
;; Open files and goto lines like we see from g++ etc. i.e. file:line
(defadvice find-file (around find-file-line-number
                             (filename &optional wildcards)
                             activate)
  "Turn files like file.cpp:14 into file.cpp and going to the 14-th line."
  (save-match-data
    (let* ((matched (string-match "^\\(.*\\):\\([0-9]+\\):?$" filename))
           (line-number (and matched
                             (match-string 2 filename)
                             (string-to-number (match-string 2 filename))))
           (filename (if matched (match-string 1 filename) filename)))
      ad-do-it
      (when line-number
        ;; goto-line is for interactive use
        (goto-char (point-min))
        (forward-line (1- line-number))))))
#+END_SRC

Unfortunately it does not work with emacsclient.
So I could use some pointers on how to make it work with emacsclient.
Would it be possible to achieve this with an advice, since the original
patch was written in c.
