README feedback about denote

Some user might do that and then wonder whey denote-link doesn't
work.

True. Will remove this part.

Additionally, if there is no identifier match, denote-link throws an
error with backtrace i.e. it's not an elegant user-error.

Better fix this then to fail gracefully. I will most likely not be able
to do this right now, as I am about to go bed. Tomorrow for sure!

I believe I fixed this while also moving the relevant code to its own file instead of keeping it in denote-link.el. The relevant part:

(defun denote-retrieve--search (regexp)
  "Search for REGEXP in the current buffer."
  (save-excursion
    (save-restriction
      (widen)
      (goto-char (point-min))
      (re-search-forward regexp nil t 1)
      (match-string-no-properties 1))))

(defun denote-retrieve--find-value (regexp)
  "Return value from REGEXP by searching the file."
  (or (denote-retrieve--search regexp)
      (user-error "Cannot retrieve %s" regexp)))

Thanks! I'll close this issue then.
