 * I have tried to set the date_class to apply multiple classes to the date (to 
   match other pages) but this doesn’t work. For example, I use
    `date_class="postdate
   bg-lightgray headerfont postmeta updated"` But the class names all get concatenated
   so the result is `<div class="postdatebg-lightgrayheaderfontpostmetaupdated">`
 * I can work around this by creating a new class and copying the attributes but
   that is not so convenient.

 * Having looked at the source, this is because it uses sanitize_html_class() to
   make sure the class is valid/safe. However, this doesn’t allow spaces. There 
   is an update of this function in progress to allow a wider range of characters.
   I have posted to the bug tracker suggesting it should also allow spaces.

 * The response to that bug report suggests using esc_attr() instead of sanitize_html_class().
   I have modified the code and this works exactly as I need. I don’t know if you
   want to make the change in your code or not …
