Apply text properties for <, > in new after-change function (C++ Java Modes).
These are category/syntax-table properties to give < and > paren syntax. Also apply certain `c-type' text properties to the insides of <..> constructs to ensure that identifiers contained by them get fontified. This patch fixes bug #681. * lisp/progmodes/cc-cmds.el (c-electric-lt-gt): Reformulate due to new after-change action. * lisp/progmodes/cc-engine.el (c-before-change-check-<>-operators): Expand change region to include <s and >s which might not be already marked as parens, rather than just when paren text properties are removed. (c-restore-<>-properties): New after-change function, which applies text properties marking < and > with paren syntax. * lisp/progmodes/cc-fonts.el (c-font-lock-declarations): Ensure `c-type' properties are applied to the interiors of <...> constructs, to ensure fontification of identifiers there. * lisp/progmodes/cc-langs.el (c-before-font-lock-functions): Add c-restore-<>-properties to this list for C++ and Java. * lisp/progmodes/cc-mode.el (c-common-init): When invoking c-before-font-lock-functions, exclude c-restore-<>-properties from the functions invoked. (c-before-change): Initialize c-new-BEG/END here (rather than c-after-change) to allow modification by before-change functions. (c-after-change): Amend c-new-END here, rather than initializing it and c-new-BEG.
