Turn off persistence until it is ready. At that point, we will need
to access the target git repo anyway, so we can keep extra metadata in
the .git directory.

See commit 74f2b2a.
Summary: this produces the
CC foo.o
lines. The idea is that long command lines distract from what is more
important, which is the compiler output. The behavior can be turned
off with “make V=1” or “make -s”.

I dunno. I included the license header instead of refering to LICENSE
because this file tends to be installed in /usr/share/doc/git/contrib
and LICENSE does not.
Maybe the file should get a simpler license? e.g.:
This file is in the public domain.
You may freely use, modify, distribute, and relicense it.

Right, this should be changed to
#include <stdlib.h>
#include "vcs-svn/svndump.h"

Sounds reasonable. Care to suggest wording?

Do version 3 dumpfiles fail?
