On my system, any branch that was created using "svn cp" of a toplevel
directory seems to cause git-svn to (rather slowly) download every
single file in the entire branch for the first commit on that branch,
giving a symptom that sounds a lot like the above "commits with
thousands of files". I assumed this was just an intentional design
decision in git-svn, to be slow and safe instead of fast and loose.
Is it actually supposed to do something smarter than that?
Thanks,
Avery
