Huh? Any format we might devise, or borrow, will have to have some
kind of escaping/quoting convention. The idea that "we don't need
that" tends to lead to very ugly workarounds later.
I do agree that the shell's quoting conventions are pretty messy
and so those aren't the ones we should borrow. We could do a lot
worse than to use some established data format like JSON or YAML.
Given that we already have src/common/jsonapi.c, it seems like
JSON would be the better choice of those two.
