Then perhaps I shouldn't make this change (and just leave it as is)
since the way real_path_internal/strbuf_realpath is written requires
that the strbuf being used for the resolved path only contains the
resolved path (see the lstat(resolved->buf &st) call). Sidenote it
looks like strbuf_getcwd() also does a reset, though more subtlety,
since it just passes its buffer to getcwd().
