A bit unclear what's going on though, would be more explicit to say:
{:count => query}, however Grit::Git#transform_options converts to this
syntax:
`--count='query'` and `git grep` can't take this syntax, it has to be:
`git grep --count query`, and this is why we're using :c, and not
:count. As {:c => query} converts to: `git grep -c 'query'` which works
as expected.
