Using Fold Keys to Open/Close Diffs in :Git

[atomdmac]

My natural inclination when working with the :Git view is to use Vim's default "folding" keys (za/zm/etc.) to open and close the various file diffs in the staged and unstaged lists.

Is this possible to do (perhaps with a custom key map)?

EDIT: It looks like this already sort of works once the diff for a particular file has been expanded. What would be nice is if I could re-map <right> and <left> arrows so that I could expand/close the file diffs using the fold keys as well.

There's no built-in functionality for this, but maps like nmap <buffer> za = in the fugitive file type should work as a reasonable approximation.

@tpope That custom key map worked beautifully. Thank you!
