NewLines appear broken in patches (Python 3, Django 1.6.1)

```
What steps will reproduce the problem?
1. have a change at the end of a line
- from:
some text
more text
- to:
some text with change
more text
2. call
d = dmp.diff_match_patch()
diffs = d.diff_main(text1, text2)
patch = d.patch_make(diffs)
print_me = d.patch_toText(patch)

What is the expected output? What do you see instead?
print_me containts:
+ with change
%0D%0Amore text

it should have contained:
+ with change
more text

What version of the product are you using? On what operating system?
- Python 3.3 x64 on Windows
- Django 1.6.1
- Chrome on Windows

Please provide any additional information below.

I could do a work-around by removing newlines but I have no idea what side
effects I'm introducing:

diffs = d.diff_main(
"".join(text1.splitlines()),
"".join(text2.splitlines())
)
```
