Subject: [PATCH] org-src: Reset buffer-modified-p after fontifying

* lisp/org-src.el (org-src-font-lock-fontify-block): Reset the
modification flag of the temporary fontification buffer after
fontifying.

Without this some modes cause Emacs to prompt about unsaved buffers
when exiting: `Save buffer *org-src-fontification:...-mode*?'
