[PATCH] git-svn now reads settings even if called in subdirectory

[Gustaf Hendeby <hendeby@isy.liu.se>]

Previously, git-svn first read the .git/config file for settings as if
current working directory was the repository top-directory, and after
that made sure to cd into top-directory.  The result was a silent
failur to read configuration settings.  This patch changes the order
these two things are done.

This fix seems a bit too obvious, which makes me think I missed
something conceptual here.  However, the patch passes "make test" and
"make full-svn-test", and the problems I had with the svn.authorsfile
setting not being honored while fetching from a subdirectory are gone.
