gunzip: fix from gzip-1.3.12 for gzip file with all zero length codes
...
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.
