>Description:
	chinese/mutt's builtin pager decides wrapping position according to
	space only, but we used to split a long line at spaces AND next to
	Big5 characters.

>How-To-Repeat:
	Send a message (to yourself) with a line like this:
	
	B5 B5B5B5B5B5B5B5B5B5B5B5B5B5B5B5B5
	                                ^ right margin
	
	mutt's pager will display:
	
	B5
	+B5B5B5B5B5B5B5B5B5B5B5B5B5B5B5B5
	
	But we like this more:
	
	B5 B5B5B5B5B5B5B5B5B5B5B5B5B5B5
	+B5B5
