Problems were caused by such a string spanning jit-lock chunks, and by a flaw in the +-500 bytes boundaries imposed for macros. * lisp/progmodes/cc-mode.el (c-extend-region-for-CPP): Check the +-500 byte macro boundaries here. (c-extend-font-lock-region-for-macros): Remove the check on the +-500 byte lower boundary. Fix the check on the upper boundary. * lisp/progmodes/cc-fonts.el (c-font-lock-raw-strings): Handle the starting point already being within a raw string. * lisp/progmodes/cc-engine.el (c-raw-string-pos) (c-depropertize-raw-strings-in-region, c-after-change-re-mark-raw-strings): Modify regexp element "\\{,16\\}" to "\\{0,16\\}" for greater compatibility with other Emacsen.a1db933c
