Not that I care, but I think `git_strarray` looks better. My personal rule of thumb is "if there's an underscore, it's a libgit2 thing".

Let's count matches : 
`find Classes -exec fgrep -E -e "- \(git_.* \*\)git_" \{\} \; | wc -l` => 19 with `git_`.
`find Classes -exec fgrep -E -e "- \(git_.* \*\)gt_" \{\} \; | wc -l` => 0 with `gt_`.

Inconsistent ? I think we're pretty good ! ;-)
