Line_Break.txt is a data file, but its use is for implementing the
Unicode Line Breaking Algorithm, which is described in UAX#14, the
Unicode Standard Annex #14.  You can find its URL at the beginning of
Line_Break.txt; I suggest to read it.  Implementing that algorithm is
something we should do, and when we do, we indeed need to import the
data in that file into Emacs and use it.  I don't see a reason to
import the data in Line_Break.txt without implementing the algorithm,
or at least most of it.
