Outline mode doesn't work if outline-regexp contains an unparenthes- ized alternative (\|). This is because outline-next-preface does (concat "[\n\^M]" outline-regexp). This is a general problem with string-form regular expressions. Why doesn't gnumacs support a Lisp-like regular expression format? e.g. [ab]\(foo\|bar\) = (concat (any "ab") (alt "foo" "bar")). This would make manipulating regular expressions much handier.
