I think this tool generates "real" renames, and seem to show up on -- e.g., if you look at the diffs for a changeset, you'll
see a file patch where the before and after names are different.

For instance, here's the bkbits diff for a patch I sent to Linus as a
normal diff (big delete + big add):|index.html|stats|!+|index.html|address@hidden|address@hidden

Notice the filenames in the diff header:

--- 1.12/drivers/serial/nb85e_uart.c    2005-02-05 00:37:24 -08:00
+++ 1.13/drivers/serial/v850e_uart.c    2005-02-05 00:37:24 -08:00

[If this is not happening for some patches, it may that Linus is
simply more lazy/busy/whatever these days and doesn't bother to use
the tool.]

Do not taunt Happy Fun Ball.
