patch 9.0.1961: 'listchars' completion misses "multispace" and "leadmultispace"

Browse Source 
Problem:  Cmdline completion for 'listchars' fields doesn't include
          "multispace" and "leadmultispace" (after 9.0.1958).
Solution: Include "multispace" and "leadmultispace" in lcstab.

closes: #13225
