vim-patch:8.2.2341: expresison command line completion incomplete after "g:"

Browse Source 
Problem:    Expresison command line completion shows variables but not
            functions after "g:". (Gary Johnson)
Solution:   Prefix "g:" when needed to a global function.
1bb4de5302

Port most of patch v8.2.0335 to complete script-local functions
if the name starts with "s:".
