Apply a few fixes from Yann's branch.
Background: I hacked on Muse over the weekend while offline, and so did
Yann. His changes to muse-wiki.el are different than the
ones that I made, so we should probably figure out the best
way to handle this when we both get on IRC again. For now,
I've merged in the bugfixes that he's made, omitting most of
the changes to muse-wiki.
* lisp/muse-latex.el (muse-latex-markup-regexps): Escape %.
* lisp/muse-wiki.el (muse-wiki-colors-wikiword): Add docstring.
* lisp/muse.el (muse-page-name): Fix a bug that was inadvertently
introduced previously.
