Oops.  That's because I put too much in the (save-excursion ...)  Here is a 
version that doesn't do that.  Testing it today I was also having a problem of 
being off by 3 lines (that's the offset), so I made a change that fixed it for 
me.  If that fix screws things up for you then you can delete the 
`(forward-line offset)` portion.

You could also add some code to delete the _region_.tex buffer, but I didn't 
think it was worth it since you're probably going to reopen it again soon 


(defadvice server-goto-line-column (after server-visit-region.tex
  "When visiting _region_.tex from an external
source (e.g. inverse search), go to the original file so that any
changes made won't be lost."
  (when (string-match "_region_.tex\\'" (buffer-file-name))
    (if (save-excursion ;; in case we don't find the other file we at least 
want the right line...
           "\message{ !name(\\([^)]+\\))\\(?: !offset(\\([-0-9]+\\))\\)?\\s *}" 
nil nil))
        (let ((file-name (match-string 1))
              (offset (match-string 2))
              (line (car (ad-get-arg 0)))
              (col (cdr (ad-get-arg 0))))
          (if offset (setq line (+ line (string-to-number offset))))
          (find-file file-name nil)
          ;; For some reason this doesn't actually go to the offset
          ;; line.  It's probably because of how advice works.
