- user wants PDF file

- with exit code other but zero there will be no PDF file

- display error or move user straight to LaTeX file to try it out
  manually or find what is wrong.

Personally I use exit code from LaTeX processing.

- I like to be careful with existing PDF files, as sometimes PDF file
  is exported in different way, and maybe I am making mistake. So I
  like to be cautious about it.

- Here below `latex-function' must return zero and `pdf-file' must
  exist for system to update it's Hyperlink correctly, and to launch
  Evince PDF viewer.

- But if error status is not zero, I want to find myself in LaTeX file
  straight, then I can try C-c C-a to understand why it did not work.

(defun hyperscope-latex-to-pdf (id)
  (let* ((default-directory (hyperscope-expand-directory-for-id id))
	 (latex-file (hyperscope-hyperdocument-file-name-full id "tex"))
	 (text (hyperscope-text id))
	 (pdf-file (hyperscope-hyperdocument-file-name-full id "pdf"))
	 (latex-function (lambda () (call-process "pdflatex" nil "*pdflatex*" nil latex-file))))
    (string-to-file-force text latex-file)
    (when (and (file-exists-p pdf-file)
	       (y-or-n-p "Delete existing PDF? "))
      (delete-file pdf-file))
    (cond ((and (zerop (funcall latex-function))
		(file-exists-p pdf-file))
	   (rcd-db-update-entry "hyobjects" "hyobjects_link" id pdf-file hs-db)
	   (hyperscope-evince pdf-file))
	  (t (rcd-warning-message "Could not create PDF")
	     (find-file latex-file)))))

If I would just assume that `latex' command "just worked", that means
I am blindly continuing with some other functions thereafter, but that
would mean I am creating some errors.
