>Description:
pkgsrc/gzip's "zgrep -h" doesn't suppress filenames like it should.  If you 
google for "zgrep -h" (with quotes) you can see others complaining about it, 
including someone complaining on the GNU gzip mailing list.  I don't see an 
official solution but I didn't search very hard.  Older versions of zgrep 
didn't have this problem.  "zgrep --no-f" works.
>How-To-Repeat:

>Fix:
My quick fix was to add -h to the --no-f check:

%%diff -C1 zgrep /tmp/zgrep
*** zgrep       Wed Dec 12 11:38:06 2007
--- /tmp/zgrep  Wed Dec 12 11:35:10 2007
