svn patch relies on the comment being present and not being localised.
See parse_diff.c:parse_next_hunk().
If we change diff_memory.c the diff parser should also be changed
to not rely on this string being present (we can't recognise
translated versions in the parser obviously).
I just checked the UNIX patch code shipped with OpenBSD and it seems
you're right that it only looks for the backslash and ignores the comment.
However, it seems in practice patches usually contain this string in
non-localised form. At least nobody has yet complained about svn patch
misparsing such patches.
