Comment:
Btw, since the topic of package maintenance cam up, we ended up carelessly including some non-POSIX extensions in our Makefile, we're in the process of reverting them https://github.com/nsxiv/nsxiv/pull/71.
This should get merged in `v28` and after this, I don't believe our build system will change much if at all. So bumping version should be a smooth experience for maintainers.
