a posix-style --version option would be very helpful, as would --help. This syntax is common enough nowadays that packages that don't support them are a little annoying (IMO). Python, etc. notwithstanding. ;) Vim is a good example - it uses '-' style options, but supports --version and --help.
I might be able to find the time to do this in the next few weeks if you think it's a good idea.
