After this change,

        git log file

will output a single commit. You can kinda fix this by passing --follow, but you need to do this every time,
there's no documented way to have it as default. Further, gitk does not appear to handle this at all, it
just shows a single revision (e.g. if run like 'gitk build/virtual-target.jam').

Then, printing past becomes inconvenient:

        $ git show 5a0d9820ac6bd4068a1fa3075d45904ed5341675:build/virtual-target.jam
        fatal: Path 'build/virtual-target.jam' exists on disk, but not in '5a0d9820ac6bd4068a1fa3075d45904ed5341675'

It is possible to use v2/build/virtual-target.jam in this case, but it's becoming not funny. And, importantly,
given that a few people said that rename should "just work", which is demonstrably false, I suspect that there
are further gotchas beyond the above immediate ones.
