git-grep: refactor defaults

Browse source 
One method to set them all... or something like that.

The defaults for git-grep options were scattered over the run
function body. This change refactors them into a separate method.
The application of defaults is checked implicitly by existing
tests and linters, and the new approach makes it very easy
to inspect the desired defaults are set.
