Interesting.  Yeah, that sounds like a bug.

I am not convinced cleaning fetched files is the right thing to do in
the first place (why not just trust the SVN repo?), but I assume
people with workflows involving such filters could make a better call.

There is no test for it in git.git, so in that sense no.

I don’t think that would be right.  It’s not just the md5sums not
matching that is the problem; it is that in these situations git-svn
and the SVN server do not agree about the file’s current content.

Once the code makes the semantics clear, I assume it should Just
Work™.

Good luck,
