git-svnimport issue with rename+change in the same commit

Hi,

I've just hit a problem when using git-svnimport to import a big subversion repository: it doesn't import correctly a commit when the commit renames (or copies) and modify a file at the same time.

At the bottom of this message, there is a script that reproduces the bug.

The result of the final 'diff' command on the script is:

diff -u --exclude .git --exclude .svn checkout/universe.py git/universe.py --- checkout/universe.py 2006-02-14 14:55:37.000000000 -0200 +++ git/universe.py 2006-02-14 14:55:38.000000000 -0200

@@ -1 +1 @@
-print "Hello, universe!"
+print "Hello, world!"

git-svnadmin is just taking the original version of the file when
the commit has a 'file copy', even if this copy was modified before
the commit.

However I can't see a way to fix this problem without making the script
ignore completely the the "copied from" information from the svn commits
(and always fetching the resulting files from the repository). It seems
that subversion doesn't tell us if the copied file was changed (or this
information is hidden somewhere else).
