Oooh, that's a good catch. If I read the diff correctly, with a
not-only-self-contained build, it will set things up such that the
Application bundle works, but the (also installed) emacs binary won't.

A solution here might be to build two pdmp files - one for the
relocatable app bundle and one for commandline usage. I'll try to build
that.

This makes sense too. I'll investigate when `Vinvocation_directory` gets
set. Does sound like that doesn't happen early enough, maybe we can pull
it forward a bit.

Thanks,
