2018-02-04gunzip: fix from gzip-1.3.12 for gzip file with all zero length codesDenys Vlasenko
Corresponding changelog from gzip-1.3.12 reads: """ 2006-12-20 Paul Eggert <eggert@cs.ucla.edu> * inflate.c (huft_build): Fix regression that caused gzip to refuse to uncompress null input (all zero length codes). Problem reported by Yiorgos Adamopoulos. This regression was caused by the security patch installed 2006-11-20, which in turn came from Debian, which in turn apparently came from Thomas Biege of SuSe.
