Regarding my point 1), I've experimented locally on my git clone to rewrite
references
to Trac tickets like "fix #1234" to become "fix
https://trac.osgeo.org/gdal/ticket/1234";
with
git filter-branch -f --msg-filter 'python /home/even/rewrite.py' -- trunk
where rewrite.py is
{{{

I'v uploaded the log of the changes (the content of /tmp/log.txt) in
http://even.rouault.free.fr/log.txt
It shows the original and modified commit messages (just for commits for which
a modification was done)
In case you have the motivation to actually review it, let me know if you see
some weird things in it...
