Indeed. A simple change in TIE§49 (or CTIE§53) prints correct line 
information related to the master file:

diff --git a/texk/web2c/tiedir/tie.w b/texk/web2c/tiedir/tie.w
index 227328b729..c91bd13ea2 100644

  if (out_mode==normal) {
      if (test_input!=none) {
         fputc(map_xchr(@'@@'),out_file); fputc(map_xchr(@'x'),out_file);
+        fprintf(out_file, " l.%ld", input_organization[0]->line);
         new_line(out_file);
          out_mode=pre;
      } else break;

Now one would have to store any manual text from the '@x' line of the 
'current' change and reproduce it in the output (if a change file is 
created).
