>Description:

	Ctags(1) overlooks some functions and macros decived by extra blanks.

	1. function

	Blanks which follows function name disturbs ctags.

	func  () {}
	     ^

	2. macro

	Blanks which follows '#' disturbs ctags.

	#  define macro() ;
	  ^

>How-To-Repeat:

	test.c
	------------------------------------------
	# define macro()        printf("Hello")
	func   ()
	{
		print("Hello");
	}
	------------------------------------------

	% ctags -x test.c
	%

	It should be like this.

	func               2 test.c           func   ()
	macro              1 test.c           # define macro()  printf("Hello")

>Fix:
	
	[/usr/src/usr.bin/ctags/C.c]
