Use of uninitialized value in concatenation (.) or string at
/usr/bin/git-svn line 1189.
GIT_CONFIG:  | GIT_DIR: .git

If I export GIT_CONFIG, then the problem goes away. Much better work
around then hardcoding svn-remote.svn.url

The git-svn fetch died overnight due to an http error. Its restarted
now. There are dozens of branches and tags in the repo, and each one
seems to take about a half hour to and hour to fully fetch. It takes a
similar amount of time to checkout trunk with tortise SVN. The repo is
local, but I don't have direct access to it.
