Fixes a problem with 9875baef (the improved merging commit), where if e.g. <C-I> exists in the dict and <Tab> doesn't, it will error with E741 on the call to extend(). I'm puzzled why this didn't occur in my earlier testing.
Broader use of s:KEYCODES and s:MERGE_INTO.
Improved the deepcopy() call in which_key#start(), will handle registration with a nested dictionary now, e.g. which_key#register('z', 'g:my_map.z'). Not sure of use-case but it works now.
Call to nr2char() replaced with which_key#char_handler#parse_raw().
