PDF extraction breaks up titles with double carriage returns

This happens for certain types of titles where a double carriage return gets inserted in the middle. For example in 8a395db08d4beeeecdca1c4cb83b93de, we have a title:

the PDF extractor puts a double carriage return between "South Sudan" and "Humanitarian..." It would be helpful to have this full title joined in a single sentence, which the double carriage return will preclude.
