 *Changes*
 + Command ~org-ql-find~ respects narrowing of the current buffer by default, allowing searching within the narrowed region.  (Using one ~C-u~ argument widens the current buffer, and using two ~C-u~ arguments prompts for the buffers to search.)
 + Function ~org-ql-completing-read~ accepts a new ~NARROWP~ argument, which is passed to ~org-ql-select~.
