This adds ability to do import "in chunks" (default 1000 revisions),
after each chunk git repo will be repacked. The option -R is used to
change default value of chunk size (or how often repository will
repacked).

Actually, I just noticed an issue here with this - it appears to be
double-importing the edge revisions.

So if I started with -s 349000 and tell it to repack every 1000
revisions, it's now importing every thousandth revision twice.

Indeed. There is the fix:

diff --git a/git-svnimport.perl b/git-svnimport.perl
index afbbe63..f1f1a7d 100755
--- a/git-svnimport.perl
+++ b/git-svnimport.perl
