PATCH: a few small completions

[Oliver Kiddle <opk@u.genie.co.uk>]

I noticed a small omission in _uncompress and _gzip which may well have already been fixed. I've also taken the opportunity to add a few new tiny completions - for whereis, (un)pack and killall. I also tried to think of any other commands for which _nothing was applicable. The only one I came up with was whoami though I found a couple more for _hosts and _users.
