You'll find it solves quite a few of your issues if you change this to
the two colon form:

      "*::option or operand:_git-dirs-_verb-arg"

When handling subcommands, it is important to drop initial arguments
from the beginning of $words to avoid confusing later calls to
_arguments. If $words contains ( git dirs init ), _arguments sees a
command and two arguments. That's what _arguments called from _git
wants but not good from _git_dirs-init.

Getting rid of the sets in _git-dirs fixes completion after git
dirs init -N. Somehow it isn't getting past the first _arguments. --help
style options can usually just be given an exclusion list of (- :)
