proxy icon and moved files

[David Reitter]

Dragging and dropping the Carbon proxy icon to a Finder window  
sometimes saves the backup file (foo.txt~) instead of the actual file.

I could reproduce this with a current build. I tried to locate the  
code that handles these things, but it's not immediately evident why  
a local copy of the file name for the frame is kept in macterm.c  
(file_name) and why it isn't updated correctly (if that is the cause).
