Re: [gentoo-dev] Re: repo/gentoo:master commit in: dev-libs/libunibreak/

If the developers of liblinebreak had not decided to rename their library, 
I could safely bump it from 2.1 to 4.0, in spite of the fact that it is 
maintainer-needed, right?
Am I personally responsible for their decision to use the new name 
libunibreak?
If there are QA problems in libunibreak-4.0.ebuild, they are surely shared 
by liblinebreak-2.1.ebuild (which is stable on amd64, ppc and x86, and 
~arm). Why these problems were not cought for many years 
liblinebreak-2.1.ebuild is in the tree? (it is there from before the git 
migration, git log only shows trivial commits not changing its 
functionality)
