this “file-name” field is not necessary.  The tarball is already
properly named.

“allowed” is a bit vague.  The description on the website is better, in
my opinion:

   Liblinebreak is an implementation of the line breaking algorithm as
   described in Unicode 6.0.0 Standard Annex 14, Revision 26. It breaks
   lines that contain Unicode characters. It is designed to be used in a
   generic text renderer.

Could you use that instead?

It’s good with these changes.
