Make --version work like "version"

[Ostrzyciel]

The usual practice is to call something -v or --version, not something version. It'd be nice to add an alias for this.

I don't like -v for this; -v is conventionally used to regulate program's verbosity.

[johnslavik]

A good shorthand flag would be -V. That's what Python uses

[Ostrzyciel]

eh, then no -v at all, good point

only --version
