Hmm, that's the right output, I think. Even though it's wrapped in single-quotes I think that's just how run_command shows it. If I do something silly like:

  [credential]
  helper = "!'git credential-store'"

then I get:

  07:07:49.063476 run-command.c:663       trace: run_command: ''\''git credential-store'\'' get'
  'git credential-store' get: 1: git credential-store: not found

So I'm quite confused about exactly what's failing and why. At this point I'd probably try running it under strace to see what's actually happening at the syscall level. I don't think you said what OS you're on; if it's Linux, then I suspect something like:

  strace -f -e execve git push

might be interesting (dropping the "-e execve" will give much more output which might also be interesting, but it's probably pretty big).
