vim-patch:8.2.1560: using NULL pointers in some code

Browse Source 
Problem:    Using NULL pointers in some code. (James McCoy)
Solution:   Avoid adding to a NULL pointer.  Use byte as unsigned.
9c2b06637b

The changes to eval.c (skip_expr_concatenate) and vim9compile.c aren't
included since they're specific to vim9script support.
