the problem seems to be with Emacs' goto-line, rather than emacsclient.
goto-line is not meant to be used by programs, as described in the
docstring, which gives an alternative. When debugging the
programme, I could see that although goto-line was being called, it
was not working as shown by the non-zero return values from the
system command (the number of lines yet to return.)
Also, see ChangeLog for Emacs 23.2 where you can see comments of the form:
2009-09-10 Glenn Morris <rgm at gnu.org>
* pcvs.el (cvs-mode-find-file): Use forward-line rather than goto-line.
I've copied the code (below) from the end of cvs-mode-find-file.
To add this to edtdb, I've changed the call on line 121 to:
cmd <- paste(
and this now works.
(defun my-goto-line (line buf)
"My version of goto-line."
(forward-line (1- line))))
