give "nbuf" strbuf a more meaningful name
It's a common pattern in our code to read paths from stdin, separated either by newlines or NULs, and unquote as necessary. In each of these five cases we use "nbuf" to temporarily store the unquoted value. Let's give it the more meaningful name "unquoted", which makes it easier to understand the purpose of the variable. While we're at it, let's also static-initialize all of our strbufs. It's not wrong to call strbuf_init, but it increases the cognitive load on the reader, who might wonder "do we sometimes avoid initializing them? why?".
