How so? Isn't it just a matter of

 git filter-branch --msg-filter 'perl -lne "
	if (/^(SVN_SILENT)[: ]*$/) { $tag = \"$1: \"; next;}
	print $tag, $_;
	$tag = \"\";"' --tag-name-filter cat -- --all

It would be a stress test to rewrite 100,000 commits with
git-filter-branch. You will need a file system that can efficiently store
and access that many files in a single directory. *That* may become the
bottleneck.

I agree somewhat as far as file contents are concerned, but commit
messages should be a help, not a hinderance.
