And here's what that would look like.

I suspect it can create its own brand of confusion, though:
$ cat `which git-broken`
#!/bin/bogus
$ git broken
git: 'broken' is not a git command. See 'git --help'.
At which point I search through my PATH and confirm that indeed,
"git-broken" _is_ a git command. And I'm left on my own to figure out
that it's a broken #!-line.
So I think I prefer giving some more specific advice. Even if we don't
mention "#!" lines explicitly, saying "This exists, but exec didn't
work" is probably more helpful than pretending it's not there. It gives
clueful people an idea of where to start looking for the problem.
