Vim emulation does not parse keystroke "a"

[mcclurgm]

The vim emulation plugin does not appear to account for the vim a (insert after cursor position) command. This is often very useful, giving users more control over where the cursor goes with fewer keystrokes.

I looked at the code in vim-emulation.vala and it appears the a keycode is not included in the switch statements. The current code includes cases for keys i and capital A and I as ways of entering insert mode. A similar case could be included to handle this keystroke.

As a Neovim user, I'd like to look into this.

I also have an PR that implements this, as well as some other functionality. It's been waiting in review: #633. Not sure what we should do about the duplicate implementations then.

Oh sorry, I didn't notice. Yours look more complete, mine can be discarded

[mcclurgm]

Perhaps, but your implementation cleans the action string, which is an improvement over mine. If you do want to discard yours, then we should implement it in mine too.

I should have commented here about my PR, so sorry for that.

On the other hand, I believe that merging this one, would just require a small rebase for your's to be valid as well.
