*foot = bullet, with gzip
Found via pkgsrc/editors/gedit:
# touch /tmp/foo
# env GZIP=`which gzip` gzip /tmp/foo
# ls -la /tmp/foo*
-rw-r--r-- 1 root wheel 24 Sep 19 22:47 /tmp/foo.gz
# ls -la /usr/bin/gzip
ls: /usr/bin/gzip: No such file or directory
# ls -la /usr/bin/gzip*
-rwxr-xr-x 1 root wheel 15093 Sep 19 22:44 /usr/bin/gzip.gz
This exists in both GNU gzip V1.3.12 and NetBSD's gzip V20060927.
Apparently neither program checks if the GZIP environment variable
contains a valid gzip option, and blindly passes its value on
to the command line.
