Implementing <n>g

[hippie68]

I suggest to implement <n>g. The alternatives <n>gg, g<n>g, and <n>G appear unnecessarily cumbersome. I think implementing <n>g should be possible, because it seems the only way to use a number with Goto is the simple Goto line number <n>.

This handy addition would be in line with the existing <n>j and <n>k, creating a more consistent experience.
