The problem is that this messes up a search in find-auto-coding:
(if (re-search-forward
"[\r\n]\\([^\r\n]*\\)[ \t]*Local Variables:[
\t]*\\([^\r\n]*\\)[\r\n]"
tail-end t)
...
(let* ((prefix (regexp-quote (match-string 1)))
(suffix (regexp-quote (match-string 2)))
The space between "Local Variables" becomes "\\(\\s-\\|\n\\)+" which is
a problem because it adds a new capturing group, which means suffix gets
the wrong value. Then we fail to find the ";; End:" line, and don't
apply the "coding: utf-8" setting.
So the value you chose isn't entirely legitimate, you should use a shy
group instead:
(equal (progn (load "international/uni-decomposition.el" t t t t)
(aref (cdr (assq 'decomposition char-code-property-alist)) 1024))
(progn (let ((search-spaces-regexp "\\(?:\\s-\\|\n\\)+"))
(load "international/uni-decomposition.el" t t t t))
(aref (cdr (assq 'decomposition char-code-property-alist)) 1024)))
;=> t
And possibly let-binding search-spaces-regexp in find-auto-coding would
make sense (although, there's probably more places like this that might
break, not sure if we can ever hope to find them all).
