 * Deep down in the TinyMCE plugin folders I found the `wordpress.css` file that
   populates the style select drop-down that one can add to the rich text editor(
   along with a format select dropdown, which is very handy). My question is, if
   I add rules to this file (which is part of the core WP files) will it be overwritten
   when I upgrade?
