* etags.c (L_isdef, L_isquote, L_getit): small optimisations.

* etags.c (L_isdef, L_isquote, L_getit): small optimisations.
	(L_funcs): the (foo::defmumble stuff now should work.
	(consider_token): function returned random value--corrected.
	(C_entries): corrected == versus = typo.
	* etags.c (FINCST): added the fignore status. Means we are
	after the parameter list and before the open curly brace.
	Allows correct parsing of C++ constructors.
	(C_entries, consider_token): make use of fignore.
	(consider_token): reset funcdef when next_token_is_func: when in
	ctags mode makes DEFVAR and others work better.
	(L_isquote): function that recognises the "(quote" string.
	(L_getit): ignore quoting via "'" or "(quote".  Useful for defalias.
