I agree with you -- I think it is extreeemely exotic, too, I only
became aware of this when I read in the documentation of `find':
,----[ (info "(find)Print File Name") ]

Nevertheless, such file names are quite easy to create: `C-x C-f foo
C-q C-j bar.txt'.

Thank you. Sorry for appearing to be nitpicking -- I only brought this
up because I try to understand the elisp (and the regexps) that I put
in my .emacs and the different styles used by different authors can be
confusing:
(add-to-list 'auto-mode-alist '("\\.org$" . org-mode))
(setq auto-mode-alist (cons '("\\.m\\'" . matlab-mode) auto-mode-alist))
Now, at least the regexp is the same. And I always use `add-to-list'
because
,----[ C-h f add-to-list RET ]
| (add-to-list LIST-VAR ELEMENT &optional APPEND COMPARE-FN)
|
| Add ELEMENT to the value of LIST-VAR if it isn't there yet.
