Patch 7.1.185
Problem:    Using "gR" with a multi-byte encoding and typing a CR pushes
	    characters onto the replace stack incorrectly, resulting in BS
	    putting back the wrong characters. (Paul B. Mahol)
Solution:   Push multi-byte characters onto the replace stack in reverse byte
	    order.  Add replace_push_mb().
Files:	    src/edit.c, src/misc1.c, src/proto/edit.pro
