When running "git svn clone" on a large repository, every a few revisions
or a single big one it stops with:
fatal: unable to run 'git-svn'
git svn fetch resumes the clone, stopping again after a few revisions. If
you keep resuming it long enough, the clone ultimately succeeds.
Thanks, Adam! Even if continually resuming with
git svn fetch isn't an elegant solution, it worked for me!
