Date: 2017-06-13
Initial Package Version: 2017-05-25
Upstream Status: Applied
Origin: Upstream
Description: Consolidated fixes for luatex.

1. Removes debugging code which was accidentally left in
luatex, which made the (infrequently needed) io.popen useless.  Also
disables io.saved_popen and changes the reported date of the luatex
version.

2. Fix for io.lines (fixed in r44572).
