I don't believe TeX is prepared to do this.  How is it supposed to
find its place in the file (plus any superior files that may be open)
assuming that you may go and modify them anywhere with the editor?

I think you may prefer to start an emacs server and send it a command
using emacsclient in your TEXEDIT envariable.  Assuming you are
running on a machine with job control or windows, that is.  Also,
isn't that syntax really for Gosling emacs?  In GNU, TeX-mode should
be entered automtically from auto-mode-alist (for any file *.tex), and
startline can be called goto-line (here we close the circle to the
beginning of this whole discussion ;-).  Better yet, however, is to
use emacs +%d switch.  Thus,

setenv TEXEDIT "gnuemacs %s +%d"
