Comment 3 for bug 753610

So the mumamo-eval-in-html-mode variable obviously has value nil when it shouldn't. When I do C-h v mumamo-eval-in-html-mode RET it tells me that the variable is defined in my desktop file, but I think that is just a consequence of desktop.el invoking the remembered major mode when it reloads the files. Still, I've expunged those files from the desktop file and will test without that factor.
