remove all trailing white space

this is just the result of

```
find -iname "*.[ch]pp" | xargs sed -i "s/ *$//"
find opm/parser/share/keywords -type f |  xargs sed -i "s/ *$//"

priority. The rationale behind this patch is that some people tell
their editor to remove white space which leads to larger than
necessary patches...
