* lisp/muse-project.el (muse-updating-file-alist-p): New variable that
prevents calls to muse-project-file-alist in its hook functions from
going into an infinite loop.
(muse-project-file-alist): Use it.
* lisp/muse-wiki.el (muse-wiki-updating-wikiword-p): Remove. This is now
handled in muse-project.el.
