when justifying, don't remove a space after a duplicate character in
punct anymore, as it doesn't really make us more compatible with Pico

 	  paragraph, to make it (partially) support multibyte

-	  do_para_begin_void() and do_para_end_void(); changes to

 	  do_justify(); removal of breakable(). (DLR)
 	- Still more steps toward full wide/multibyte character support.
