We use manual computation and strcpy to allocate the "root"
variable. This would be much simpler using xstrfmt. But
since we store the length, too, we can just use a strbuf,
which handles that for us.
Note that we stop distinguishing between "no root" and
"empty root" in some cases, but that's OK; the results are
the same (e.g., inserting an empty string is a noop).
