Git is not a shell. And I'm sure it is not the only program that has this
issue. "Don't do it, then."

Git's implementation depends on the system's execvp behavior. As it
stands, current implementations of execvp path lookup and of popular
shells' path lookup differ in this respect. Bad luck. Don't check the
sanity of your PATH by testing how your shell looks up executables.
