Got a copy of the gnu diff for Windows, and the output of

diff --unified=1 test.txt test_v2.txt > out

looks different than what Subversion produces. The second chunk starts with
@@ -4,9 +7,9 @@
instead of
@@ -2,9 +5,9 @@

which is also what TortoiseMerge expects.

The full output of gnu diff for those two files:
