I moved a bunch of SATA drivers in the Linux kernel from drivers/scsi to

When I tried to look at the past history of a file using git-whatchanged,
post-rename, it only shows the history from HEAD to the point of rename.
Everything prior to the rename is lost.
I also tried git-whatchanged on the old path, but that produces an error.
For filenames that don't exist right now, you need to clearly separate the
revision name from the filename (ie you need to use "--").
There were patches to do "--follow-rename" which I don't think got applied
yet, but in the meantime, just do
git whatchanged -M -- drivers/ata/filename.c drivers/scsi/filename.c
where the "-M" means "show diffs as renames if possible" (which is
different from having the history actually _follow_ them), and the "--" is
the filename separator to tell git that the nonexistent
"drivers/ata/filename.c" file isn't a (currently) nonexistent revision
name, it's a (currently) nonexistent _filename_.
Since I'm just interested in the log (ATM), even the lack of "-M" seems
to produce useful results. Thanks.
IMO it is highly counter-intuitive that renames are -not- followed. I
don't see the point of a "--follow-rename", it should Just Work(tm).
