Subject:	gzip-1.7-1 regression: cannot redirect output of gzip -l
MIME-Version:	1.0
X-IsSubscribed:	yes
X-MIME-Autoconverted:	from quoted-printable to 8bit by delorie.com id u3J9nbQc000452

gzip-1.7-1 reports a write error if result of -l is redirected:

$ uname -srvm
CYGWIN_NT-6.1-WOW 2.5.0(0.297/5/3) 2016-04-11 09:55 i686

$ cygcheck -f /bin/gzip
gzip-1.7-1

$ echo text | gzip > text.gz

$ gzip -l text.gz
         compressed        uncompressed  ratio uncompressed_name
                 25                   5 -40.0% text

$ gzip -l text.gz | cat
gzip: write error: Bad file descriptor

$ gzip -l text.gz > out
gzip: write error: Bad file descriptor

This breaks (at least) the zforce script.

gzip -c is not affected.
