    Improve regexp for looking for documentclass macro
    
    * latex.el (LaTeX-env-document): Allow any non line-breaking character in 
regexp
      used to look for `documentclass' macro.  Previous regexp did not catch 
class
      options containing dots or slash, that may occur when using `subfiles' 
class.
