That said, rename detection is based on heuristics and shaped by one or
more configuration knobs. So it is wise to either understand that
heuristics [1] well or to keep rename commits somewhat "isolated"
(personally, I tend to not make (biggish) changes in the file(s) I'm
renaming in the same commit. YMMV, heuristically, of course.

I also have acquired the custom to use "git mv" and friends, be it to
remind myself that I'm doing it under VC (and to keep that peripheral
eye to whether VC is doing what I think it does).

[1] some similarity measure plus some threshold. There are also rumours
   of massive renames hitting some limits.
