Yeah, I think that is a readability improvement. I suppose the use-site
could also just run "file_exists" itself, but I wanted to keep the
filesystem-reading "magic name" bits together.

I had also originally considered adding new states to "whence" to cover
these cases (i.e., FROM_CHERRY_PICK_MULTI), but there are fallouts all
over the place for call sites that do not care whether we are in the
single- or multi-commit mode.
