I've been using mac os x for several years, and I realize that I've now gotten used to all applications transparently "following" files as I rename or move them (either via mv on the console or within the Finder's GUI), and emacs is pretty much the only program that does not.

This is a shame though, because most of my time in front a screen is actually spent in front of emacs :-)

Would anyone have any ideas or pointers about what measures I could take to get that behaviour in emacs ?

(yes I know this is "impossible" to acheive in general, but when I just rename a simple file, or move it to a directory nearby, it's a shame I have to close/reopen it for emacs to notice. oh and no, I'm not going to use 'dired' as a file manager :-)
