I had it in my head that such a strategy was supposed to be a temporary
step in the process of getting rid of dashed forms. That is, you can do
that now to avoid having your scripts break, but in the long run, you
should be converting to the space form.

But I guess the plan was softened, and we have no deprecation plan for
dashed forms in exec-path. So maybe my thinking was outdated.

I can see that for a totally third-party script which wanted to use git
plumbing.  But why do that for a git-* script? The "git" wrapper sets up
the environment like that already.
