bug#20771: 25.0.50; elisp completion-at-point can't complete #' quoted function names

[Michael Heerdegen]

Hello,

in scratch, or any emacs-lisp-mode buffer, insert

  (list #'make-frame-comma)

and put point directly before the closing paren.  Hit C-M-i, you get [No
match].  This doesn't seem to be useful or intended.

Looking at the code, the #' quoting style case seems not to be handled
specially, the "#'" seems to be treated as like being part of the
symbol name:

(mapcar (lambda (string)
          (with-temp-buffer
            (insert string)
            (pcase (elisp-completion-at-point)
              (`(,beg ,end . ,_)
               (buffer-substring-no-properties beg end)))))
        '("'make-fr" "#'make-fr"))

==> ("make-fr" "#'make-fr")


Thanks in advance,

Michael.
