+Is this the right solution?  Need to cleanup langmap behavior:
+- in vgetorpeek() apply langmap to the typeahead buffer and put the result in
+  a copy-buffer, only when langmap is appropriate for the current mode. Then

+- Remove LANGMAP_ADJUST() in other parts of the code.  Make sure the mode is

+So that replaying the register doesn't use keymap/langmap and still does the
