I've just committed some optimisations to the savannah master branch which should speed up the handling of long C++ raw strings in an Emacs where font-locking is fully working. On a megabyte long raw string in a normal build on a reasonably modern machine, the response is slightly sluggish, but not unreasonable to somebody who prefers correct fontification to instant response. -- Alan Mackenzie (Nuremberg, Germany).
