The scripts do not update their PATH. `git` does, before they are called.

For example, if you call `git stash`, the `git` executable will first
figure out that `stash` is not a builtin (unless you run with the
experimental patch series that still has not seen much review, more is the
shame, including on myself), and then call the dashed form. At this point,
`git` will already have added the exec path to the PATH variable so that
`git-stash` is found. So then `git-stash` runs, and does not even need to
take pains to adjust the PATH variable again! Magic!
