Vi mode and g commands

[Dan Shearer]

Some g commands are implemented, but incorrectly. Examples:
* g0 is equivalent to 0, rather than 'beginning of screen line when wrapped'
* g$ is equivalent to $, rather than 'end of screen line when wrapped'

Other g commands are not implemented, just ignored. Examples:
* gM is ignored, rather than going to the middle of the line
* gE is ignored, rather than going to the end of the last word
