svn log line deltas

Hi there,

I've migrated from cvs to subversion for several projects I maintain.
Before migration I used the statcvs-xml (http://statcvs-xml.berlios.de)
project tracing tool to get great reports of developer cvs usage and
statistics (several metrics are supported by statcvs-xml) until migration.
statcvs-xml uses cvs log output to generate it's metrics.

One important semantic difference between svn and cvs log capabilities I
noticed so long (relevant for statcvs) is that svn log does not support
source based line change deltas as cvs does (e.g. -20 +50).
But most metrics about version control are based on developer based line
change deltas, I think.

So I googled around and found following thread discussed on this list a
month ago:

http://www.contactor.se/~dast/svnusers/archive-2004-02/0297.shtml

Following this thread, it seems that deltas won't be supported in future
by svn?

I tried svn diff -r X and counting ^+ and ^-, but this is pretty
annoying and provides no sufficient information about history based line
deltas (only deltas between two revisions).

Do you know any other way to get sufficient information from svn about
deltas of changed lines for arbritrary revisions and the whole revision
history (like cvs log does)?

Regards,
