I am really wondering, when -R is used, how the file rename/copy
should defined? Now, I can make -R works with --follow, and it produce
something like:

byang@byang-laptop:~/git/git$ ./git diff --follow --name-status maint
master -- builtin/log.c
R089    builtin-log.c   builtin/log.c
byang@byang-laptop:~/git/git$ ./git diff --follow --name-status -R
maint master -- builtin/log.c
R089    builtin/log.c   builtin-log.c
byang@byang-laptop:~/git/git$ ./git diff --follow --name-status
master maint -- builtin/log.c
D       builtin/log.c
byang@byang-laptop:~/git/git$ ./git diff --follow --name-status -R
master maint -- builtin/log.c
A       builtin/log.c


The problem is whether it make sense to say 'builtin/log.c renamed to
builtin-log.c' when -R is given?

Regards!
