Or realizing that Free Software means legal stuff, we need to modify this and 
add a legal notice about the GPL, a copyright years notice, and options to 
handle --help and --version. Because Wget's standard help cannot be used here.
The script needs to eliminate any -O options passed to zcat.

Also, if such a script is to go into productions systems, it needs more sanity 
checks for, as previously mentioned, other -O options among a couple of other 
things.

I was just looking at the source for zcat. It's technically a one line shell 
script:
exec gzip -cd "$@"

However, the rest of cruft adds another 55 lines.

And talking about legalities, I'm hoping you already have signed the assignment 
papers because otherwise that's even more work, before we can add this to the 
source. :-)
