The bug is not present in the original LSM data (as I showed in another comment), but
is present in the JSON data¹:
{"author":"Manuel.Serrano@inria.fr (Manuel Serrano)","primary-site":"ftp.inria.fr /INRIA/Projects/icsla4048000 bigloo1.3b.tar.Z\n","maintained-by":"Manuel.Serrano@inria.fr","entered-date":"1996-01-01","version":"1.3","keywords":"","original-site":"","description":"Bigloo is both a interpreter and a compiler. It is conformantto IEEE Scheme standard with some extensions from which we can\nsite regular parsing or pattern matching.\n","copying-policy":"Copyleft","platforms":"","alternate-site":"","title":"\"Bigloo, a Scheme to C compiler\""}
You can see that the same bug is also affecting other multi-line fields, like “Primary-site” here, and “Alternate-site” for other projects.
