The diff against v4 is kinda big but it's mostly about converting
`...` to $(...) and making git_path() and friends return a const
string.
Another notable change is I no longer attempt to support checkouts on
portable devices. Torsten pointed out (privately) that my dealing with
Windows drives was insufficient. And Junio was not so happy with how
link() was handled either. We can revisit it later.
Many thanks to Eric, who was very patient to go through the series
carefully and pointed out problems that I overlooked.
