git-svn fetch fails when a file is renamed changing only case

For example, if you had a file named TestFile and it's renamed to 
TESTFILE, git-svn fails to fetch revisions after the rename.

My perl skills are close to non-existant, so I'm afraid I don't know how 
to fix this. Attached to this message, however, is a sample svn 
repository that can reproduce this bug. Just unpack it somewhere (let's 
say, in /tmp) and try the following:

tar -C /tmp -xzf git-svn-rename-test.tar.gz
mkdir test-wc
cd test-wc
git-svn init file:///tmp/git-svn-rename-test
git-svn fetch

The last command will fail after fetching revision #3, where a file 
named TestFile was renamed to TESTFILE. Here's the stack trace:

svn: 'TestFile' is not under version control

Ah, the problem is that git-svn relies on git-diff-files and
git-ls-files to track changes when using the command-line svn client.
git itself is a case-sensitive file-system, but git-svn relies on the
working tree if you didn't have the SVN libraries, and successfully
stats the 'TestFile' even though it no longer exists (and is replaced
by 'TESTFILE').

Good to know that the SVN:: libraries are working for you, though.
