Thanks, the prolbem with \1 is solved but then the function only finds
first occurrence of \include{filename} and then I get in the echo buffer: 
while: Search failed: "\\\\include{\\(.*\\)}"

Now my function is:
(defun my-document-files ()
  "Open all document files"
  (interactive)
  (while (re-search-forward "\\\\include{\\(.*\\)}")
	 (find-file (concat "~/nauka/doktorat/thesis/" (match-string 1) ".tex"))))

why it failed although I have much more occurences of \include{...} in
the main.tex file? Any idea?
