[RFC/PATCH v2 7/8] completion: get rid of __gitcomp_1

[Felipe Contreras <felipe.contreras@gmail.com>]

There's no point in calling a separate function that is only used in one
place. Specially considering that there's no need to call compgen, and
we traverse the words ourselves both in __gitcompadd, and __gitcomp_1.

So lets squash the functions together, and traverse only once.

This improves performance.

No functional changes.
