Done.

> Something that i tried out of the box and that gave me a weird result was "./words --help". It listed words from awk i think, which is a bit odd. But since it is a basic script, it's not a big deal.

Fixed by adding -- to the awk command line.

Now prints:
...
$ ./gdb/contrib/words.sh --help
awk: /tmp/tmp.XttLdZXpeI:2: fatal: cannot open file `--help' for reading (No such file or directory)
...
