The .po files from the Translation Project come with unwrapped strings so this matches it. This may reduce the noise in diffs too. When the beginning of a paragraph had changed, the rest of the lines got rewrapped in msgsid. Now it's just one very long line that changes when a paragraph has been edited. The --add-location=file option was removed as redundant. The line numbers don't exist in the .pot file due to --porefs file and thus they cannot get copied to the .po files either.
