User edited document. Trying to view a diff at URL at our site
`phriction/diff/8/?l=2&r=3`
gives following error message:
```
Diff Parse Exception: Expected '\ No newline at end of file'.
43
.
. < actual diff here >
.
47
>>> 48 \ Kein Zeilenumbruch am Dateiende.
```
Note that I removed the actual diff content. I think the relevant issue is the last line, where some software seems to expect a string in English that has been generated in German.
Checking environment variables show that `LANG` is set to `de_DE.UTF-8`
I believe that looking at diffs in phriction worked before on this machine, but I might be wrong.
