[luatex] No hyphenation when \lccodes zero with explicit hyphens

[Thomas Fischer]

Hello,

in LuaTeX's bug tracker (see link below), this issue has been reported as fixed. However, despite using luatex 0.80, I can still reproduce this issue.
Apprarently, I am not the only one who is affected. For example, see this comment on LaTeX Stack Exchange:
http://tex.stackexchange.com/questions/229896/is-it-possible-to-allow-linebreaks-in-the-isbn-number-of-auto-generated-biblio#comment719972_229896

My luatex version reports itself as:
This is LuaTeX, Version beta-0.80.0 (TeX Live 2015/Arch Linux) (rev 5238)

Is my version still too old or is the bug maybe not yet completely fixed?

Bye,
Thomas
