Makes me wonder if `setup_git_directory_gently()` should BUG if it
receives NULL. That would require some reshuffling in setup.c, since
`setup_git_directory()` calls out to it with NULL... Just thinking out
loud. In any case, and more importantly, this is the last user providing
NULL except for the one in `setup_git_directory()`.

A small while-at-it conversion from subshell (with a funny pipe into it)
to `-C sub`. The `rm -fr` invocation is not in the original, so
shouldn't be needed. This one looks safe enough, though it makes me
wonder why you need it. `mkdir -p sub`? Probably not worth a v2.

Nice.
