I don't think Stephen's patch ever gets triggered, either.

This section of code was done by Andy, so I can't tell his motivations
for using 'unknown' the way he did.

$email does appear to get set correctly for the first two elsifs cases
here in the existing code:

		if (!defined $name_field) {
			#
		} elsif ($name_field =~ /(.*?)\s+<(.*)>/) {
			($name, $email) = ($1, $2);
		} elsif ($name_field =~ /(.*)@/) {
			($name, $email) = ($1, $name_field);
		} else {
			($name, $email) = ($name_field, $name_field);

So I propose the following one-line change instead of Stephen's:

diff --git a/git-svn.perl b/git-svn.perl
index b151049..301a5b4 100755
--- a/git-svn.perl
+++ b/git-svn.perl
@@ -2432,7 +2432,7 @@ sub make_log_entry {
 		} elsif ($name_field =~ /(.*)@/) {
 			($name, $email) = ($1, $name_field);
 		} else {
-			($name, $email) = ($name_field, 'unknown');
+			($name, $email) = ($name_field, $name_field);
 		}
 	}
 	if (defined $headrev && $self->use_svm_props) {
