Adding an "eval" here will subtly change the behavior for other shells.
Right now they'd just do whitespace splitting (which presumably busybox
is not), but with this we'd expand metachars, etc.
I suspect that's fine (and maybe even preferable, because if you really
do have a space in the path you can actually escape it). So I don't mind
this change.
I do worry that this whitespace splitting behavior could bite us in
other scripts. Curiously, my version of busybox (1.30.1) doesn't seem to
have any problem with it, though.
