I just wanted to point out that it works fine when specifying the *original*
file name (which kind of makes sense given that everything is done in reverse
order):
$ git init >/dev/null
$ echo foo >a && git add a && git commit -m first
[master (root-commit) 3631134] first
1 file changed, 1 insertion(+)
create mode 100644 a
$ echo bar >b && git add b && git commit -m second
[master 7772184] second
1 file changed, 1 insertion(+)
create mode 100644 b
$ git mv b c && git commit -m third
[master 0275097] third
1 file changed, 0 insertions(+), 0 deletions(-)
rename b => c (100%)
$ git log --oneline --follow --reverse -- c
0275097 third
$ git log --oneline --follow --reverse -- b
7772184 second
0275097 third
However, that also doesn't seem to work for builtin/clone.c:
$ git log --oneline --follow --reverse -- builtin-clone.c | wc -l
